+ - Log messages to explain your changes are as important as the
+ changes themselves. Clearly written code and in-code comments
+ explain how the code works and what is assumed from the surrounding
+ context. The log messages explain what the changes wanted to
+ achieve and why the changes were necessary (more on this in the
+ accompanying SubmittingPatches document).
+
Make your code readable and sensible, and don't try to be clever.
As for more concrete guidelines, just imitate the existing code
. since mid 2017 with 512f41cf, we have been using designated
initializers for array (e.g. "int array[10] = { [5] = 2 }").
+ . since early 2021 with 765dc168882, we have been using variadic
+ macros, mostly for printf-like trace and debug macros.
+
These used to be forbidden, but we have not heard any breakage
report, and they are assumed to be safe.

+Git 2.36 Release Notes
+======================
+
+Updates since Git 2.35
+----------------------
+
+Backward compatibility warts
+
+ * "git name-rev --stdin" has been deprecated and issues a warning
+ when used; use "git name-rev --annotate-stdin" instead.
+
+ * "git clone --filter=... --recurse-submodules" only makes the
+ top-level a partial clone, while submodules are fully cloned. This
+ behaviour is changed to pass the same filter down to the submodules.
+
+
+Note to those who build from the source
+
+ * Since Git 2.31, our source assumed that the compiler you use to
+ build Git supports variadic macros, with an easy-to-use escape
+ hatch to allow compilation without variadic macros with an request
+ to report that you had to use the escape hatch to the list.
+ Because we haven't heard from anybody who actually needed to use
+ the escape hatch, it has been removed, making support of variadic
+ macros a hard requirement.
+
+
+UI, Workflows & Features
+
+ * Assorted updates to "git cat-file", especially "-h".
+
+ * The command line completion (in contrib/) learns to complete
+ arguments to give to "git sparse-checkout" command.
+
+ * "git log --remerge-diff" shows the difference from mechanical merge
+ result and the result that is actually recorded in a merge commit.
+
+ * "git log" and friends learned an option --exclude-first-parent-only
+ to propagate UNINTERESTING bit down only along the first-parent
+ chain, just like --first-parent option shows commits that lack the
+ UNINTERESTING bit only along the first-parent chain.
+
+ * The command line completion script (in contrib/) learned to
+ complete all Git subcommands, including the ones that are normally
+ hidden, when GIT_COMPLETION_SHOW_ALL_COMMANDS is used.
+
+ * "git branch" learned the "--recurse-submodules" option.
+
+ * A not-so-common mistake is to write a script to feed "git bisect
+ run" without making it executable, in which case all tests will
+ exit with 126 or 127 error codes, even on revisions that are marked
+ as good. Try to recognize this situation and stop iteration early.
+
+ * When "index-pack" dies due to incoming data exceeding the maximum
+ allowed input size, include the value of the limit in the error
+ message.
+
+ * The error message given by "git switch HEAD~4" has been clarified
+ to suggest the "--detach" option that is required.
+
+ * In sparse-checkouts, files mis-marked as missing from the working tree
+ could lead to later problems. Such files were hard to discover, and
+ harder to correct. Automatically detecting and correcting the marking
+ of such files has been added to avoid these problems.
+
+ * "git cat-file" learns "--batch-command" mode, which is a more
+ flexible interface than the existing "--batch" or "--batch-check"
+ modes, to allow different kinds of inquiries made.
+
+ * The level of verbose output from the ort backend during inner merge
+ has been aligned to that of the recursive backend.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * "git apply" (ab)used the util pointer of the string-list to keep
+ track of how each symbolic link needs to be handled, which has been
+ simplified by using strset.
+
+ * Fix a hand-rolled alloca() imitation that may have violated
+ alignment requirement of data being sorted in compatibility
+ implementation of qsort_s() and stable qsort().
+
+ * Use the parse-options API in "git reflog" command.
+
+ * The conditional inclusion mechanism of configuration files using
+ "[includeIf <condition>]" learns to base its decision on the
+ URL of the remote repository the repository interacts with.
+ (merge 399b198489 jt/conditional-config-on-remote-url later to maint).
+
+ * "git name-rev --stdin" does not behave like usual "--stdin" at
+ all. Start the process of renaming it to "--annotate-stdin".
+ (merge a2585719b3 jc/name-rev-stdin later to maint).
+
+ * "git update-index", "git checkout-index", and "git clean" are
+ taught to work better with the sparse checkout feature.
+
+ * Use an internal call to reset_head() helper function instead of
+ spawning "git checkout" in "rebase", and update code paths that are
+ involved in the change.
+
+ * Messages "ort" merge backend prepares while dealing with conflicted
+ paths were unnecessarily confusing since it did not differentiate
+ inner merges and outer merges.
+
+ * Small modernization of the rerere-train script (in contrib/).
+
+ * Use designated initializers we started using in mid 2017 in more
+ parts of the codebase that are relatively quiescent.
+
+ * Improve failure case behaviour of xdiff library when memory
+ allocation fails.
+
+ * General clean-up in reftable implementation, including
+ clarification of the API documentation, tightening the code to
+ honor documented length limit, etc.
+
+ * Remove the escape hatch we added when we introduced the weather
+ balloon to use variadic macros unconditionally, to make it official
+ that we now have a hard dependency on the feature.
+
+ * Makefile refactoring with a bit of suffixes rule stripping to
+ optimize the runtime overhead.
+
+
+Fixes since v2.35
+-----------------
+
+ * "rebase" and "stash" in secondary worktrees are broken in
+ Git 2.35.0, which has been corrected.
+
+ * "git pull --rebase" ignored the rebase.autostash configuration
+ variable when the remote history is a descendant of our history,
+ which has been corrected.
+ (merge 3013d98d7a pb/pull-rebase-autostash-fix later to maint).
+
+ * "git update-index --refresh" has been taught to deal better with
+ racy timestamps (just like "git status" already does).
+ (merge 2ede073fd2 ms/update-index-racy later to maint).
+
+ * Avoid tests that are run under GIT_TRACE2 set from failing
+ unnecessarily.
+ (merge 944d808e42 js/test-unset-trace2-parents later to maint).
+
+ * The merge-ort misbehaved when merge.renameLimit configuration is
+ set too low and failed to find all renames.
+ (merge 9ae39fef7f en/merge-ort-restart-optim-fix later to maint).
+
+ * We explain that revs come first before the pathspec among command
+ line arguments, but did not spell out that dashed options come
+ before other args, which has been corrected.
+ (merge c11f95010c tl/doc-cli-options-first later to maint).
+
+ * "git add -p" rewritten in C regressed hunk splitting in some cases,
+ which has been corrected.
+ (merge 7008ddc645 pw/add-p-hunk-split-fix later to maint).
+
+ * "git fetch --negotiate-only" is an internal command used by "git
+ push" to figure out which part of our history is missing from the
+ other side. It should never recurse into submodules even when
+ fetch.recursesubmodules configuration variable is set, nor it
+ should trigger "gc". The code has been tightened up to ensure it
+ only does common ancestry discovery and nothing else.
+ (merge de4eaae63a gc/fetch-negotiate-only-early-return later to maint).
+
+ * The code path that verifies signatures made with ssh were made to
+ work better on a system with CRLF line endings.
+ (merge caeef01ea7 fs/ssh-signing-crlf later to maint).
+
+ * "git sparse-checkout init" failed to write into $GIT_DIR/info
+ directory when the repository was created without one, which has
+ been corrected to auto-create it.
+ (merge 7f44842ac1 jt/sparse-checkout-leading-dir-fix later to maint).
+
+ * Cloning from a repository that does not yet have any branches or
+ tags but has other refs resulted in a "remote transport reported
+ error", which has been corrected.
+ (merge dccea605b6 jt/clone-not-quite-empty later to maint).
+
+ * Mark in various places in the code that the sparse index and the
+ split index features are mutually incompatible.
+ (merge 451b66c533 js/sparse-vs-split-index later to maint).
+
+ * Update the logic to compute alignment requirement for our mem-pool.
+ (merge e38bcc66d8 jc/mem-pool-alignment later to maint).
+
+ * Pick a better random number generator and use it when we prepare
+ temporary filenames.
+ (merge 47efda967c bc/csprng-mktemps later to maint).
+
+ * Update the contributor-facing documents on proposed log messages.
+ (merge cdba0295b0 jc/doc-log-messages later to maint).
+
+ * When "git fetch --prune" failed to prune the refs it wanted to
+ prune, the command issued error messages but exited with exit
+ status 0, which has been corrected.
+ (merge c9e04d905e tg/fetch-prune-exit-code-fix later to maint).
+
+ * Problems identified by Coverity in the reftable code have been
+ corrected.
+ (merge 01033de49f hn/reftable-coverity-fixes later to maint).
+
+ * A bug that made multi-pack bitmap and the object order out-of-sync,
+ making the .midx data corrupt, has been fixed.
+ (merge f8b60cf99b tb/midx-bitmap-corruption-fix later to maint).
+
+ * The build procedure has been taught to notice older version of zlib
+ and enable our replacement uncompress2() automatically.
+ (merge 07564773c2 ab/auto-detect-zlib-compress2 later to maint).
+
+ * Interaction between fetch.negotiationAlgorithm and
+ feature.experimental configuration variables has been corrected.
+ (merge 714edc620c en/fetch-negotiation-default-fix later to maint).
+
+ * "git diff --diff-filter=aR" is now parsed correctly.
+ (merge 75408ca949 js/diff-filter-negation-fix later to maint).
+
+ * When "git subtree" wants to create a merge, it used "git merge" and
+ let it be affected by end-user's "merge.ff" configuration, which
+ has been corrected.
+ (merge 9158a3564a tk/subtree-merge-not-ff-only later to maint).
+
+ * Unlike "git apply", "git patch-id" did not handle patches with
+ hunks that has only 1 line in either preimage or postimage, which
+ has been corrected.
+ (merge 757e75c81e jz/patch-id-hunk-header-parsing-fix later to maint).
+
+ * "receive-pack" checks if it will do any ref updates (various
+ conditions could reject a push) before received objects are taken
+ out of the temporary directory used for quarantine purposes, so
+ that a push that is known-to-fail will not leave crufts that a
+ future "gc" needs to clean up.
+ (merge 5407764069 cb/clear-quarantine-early-on-all-ref-update-errors later to maint).
+
+ * Because a deletion of ref would need to remove it from both the
+ loose ref store and the packed ref store, a delete-ref operation
+ that logically removes one ref may end up invoking ref-transaction
+ hook twice, which has been corrected.
+ (merge 2ed1b64ebd ps/avoid-unnecessary-hook-invocation-with-packed-refs later to maint).
+
+ * When there is no object to write .bitmap file for, "git
+ multi-pack-index" triggered an error, instead of just skipping,
+ which has been corrected.
+ (merge eb57277ba3 tb/midx-no-bitmap-for-no-objects later to maint).
+
+ * "git cmd -h" outside a repository should error out cleanly for many
+ commands, but instead it hit a BUG(), which has been corrected.
+ (merge 87ad07d735 js/short-help-outside-repo-fix later to maint).
+
+ * "working tree" and "per-worktree ref" were in glossary, but
+ "worktree" itself wasn't, which has been corrected.
+ (merge 2df5387ed0 jc/glossary-worktree later to maint).
+
+ * L10n support for a few error messages.
+ (merge 3d3c23b3a7 bs/forbid-i18n-of-protocol-token-in-fetch-pack later to maint).
+
+ * Test modernization.
+ (merge d4fe066e4b sy/t0001-use-path-is-helper later to maint).
+
+ * "git log --graph --graph" used to leak a graph structure, and there
+ was no way to countermand "--graph" that appear earlier on the
+ command line. A "--no-graph" option has been added and resource
+ leakage has been plugged.
+
+ * Error output given in response to an ambiguous object name has been
+ improved.
+ (merge 3a73c1dfaf ab/ambiguous-object-name later to maint).
+
+ * "git sparse-checkout" wants to work with per-worktree configuration,
+ but did not work well in a worktree attached to a bare repository.
+ (merge 3ce1138272 ds/sparse-checkout-requires-per-worktree-config later to maint).
+
+ * Setting core.untrackedCache to true failed to add the untracked
+ cache extension to the index.
+
+ * Workaround we have for versions of PCRE2 before their version 10.36
+ were in effect only for their versions newer than 10.36 by mistake,
+ which has been corrected.
+ (merge 97169fc361 rs/pcre-invalid-utf8-fix-fix later to maint).
+
+ * Document Taylor as a new member of Git PLC at SFC. Welcome.
+ (merge e8d56ca863 tb/coc-plc-update later to maint).
+
+ * "git checkout -b branch/with/multi/level/name && git stash" only
+ recorded the last level component of the branch name, which has
+ been corrected.
+
+ * "git fetch" can make two separate fetches, but ref updates coming
+ from them were in two separate ref transactions under "--atomic",
+ which has been corrected.
+
+ * Check the return value from parse_tree_indirect() to turn segfaults
+ into calls to die().
+ (merge 8d2eaf649a gc/parse-tree-indirect-errors later to maint).
+
+ * Newer version of GPGSM changed its output in a backward
+ incompatible way to break our code that parses its output. It also
+ added more processes our tests need to kill when cleaning up.
+ Adjustments have been made to accommodate these changes.
+ (merge b0b70d54c4 fs/gpgsm-update later to maint).
+
+ * Other code cleanup, docfix, build fix, etc.
+ (merge cfc5cf428b jc/find-header later to maint).
+ (merge 40e7cfdd46 jh/p4-fix-use-of-process-error-exception later to maint).

[[describe-changes]]
=== Describe your changes well.
+The log message that explains your changes is just as important as the
+changes themselves. Your code may be clearly written with in-code
+comment to sufficiently explain how it works with the surrounding
+code, but those who need to fix or enhance your code in the future
+will need to know _why_ your code does what it does, for a few
+reasons:
+
+. Your code may be doing something differently from what you wanted it
+ to do. Writing down what you actually wanted to achieve will help
+ them fix your code and make it do what it should have been doing
+ (also, you often discover your own bugs yourself, while writing the
+ log message to summarize the thought behind it).
+
+. Your code may be doing things that were only necessary for your
+ immediate needs (e.g. "do X to directories" without implementing or
+ even designing what is to be done on files). Writing down why you
+ excluded what the code does not do will help guide future developers.
+ Writing down "we do X to directories, because directories have
+ characteristic Y" would help them infer "oh, files also have the same
+ characteristic Y, so perhaps doing X to them would also make sense?".
+ Saying "we don't do the same X to files, because ..." will help them
+ decide if the reasoning is sound (in which case they do not waste
+ time extending your code to cover files), or reason differently (in
+ which case, they can explain why they extend your code to cover
+ files, too).
+
+The goal of your log message is to convey the _why_ behind your
+change to help future developers.
+
The first line of the commit message should be a short description (50
characters is the soft limit, see DISCUSSION in linkgit:git-commit[1]),
and should skip the full stop. It is also conventional in most cases to
. alternate solutions considered but discarded, if any.
+[[present-tense]]
+The problem statement that describes the status quo is written in the
+present tense. Write "The code does X when it is given input Y",
+instead of "The code used to do Y when given input X". You do not
+have to say "Currently"---the status quo in the problem statement is
+about the code _without_ your change, by project convention.
+
[[imperative-mood]]
Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
organized hierarchically and you would like to apply a configuration to
all the branches in that hierarchy.
+`hasconfig:remote.*.url:`::
+ The data that follows this keyword is taken to
+ be a pattern with standard globbing wildcards and two
+ additional ones, `**/` and `/**`, that can match multiple
+ components. The first time this keyword is seen, the rest of
+ the config files will be scanned for remote URLs (without
+ applying any values). If there exists at least one remote URL
+ that matches this pattern, the include condition is met.
++
+Files included by this option (directly or indirectly) are not allowed
+to contain remote URLs.
++
+Note that unlike other includeIf conditions, resolving this condition
+relies on information that is not yet known at the point of reading the
+condition. A typical use case is this option being present as a
+system-level or global-level config, and the remote URL being in a
+local-level config; hence the need to scan ahead when resolving this
+condition. In order to avoid the chicken-and-egg problem in which
+potentially-included files can affect whether such files are potentially
+included, Git breaks the cycle by prohibiting these files from affecting
+the resolution of these conditions (thus, prohibiting them from
+declaring remote URLs).
++
+As for the naming of this keyword, it is for forwards compatibiliy with
+a naming scheme that supports more variable-based include conditions,
+but currently Git only supports the exact keyword described above.
+
A few more notes on matching via `gitdir` and `gitdir/i`:
* Symlinks in `$GIT_DIR` are not resolved before matching.

+
+extensions.worktreeConfig::
+ If enabled, then worktrees will load config settings from the
+ `$GIT_DIR/config.worktree` file in addition to the
+ `$GIT_COMMON_DIR/config` file. Note that `$GIT_COMMON_DIR` and
+ `$GIT_DIR` are the same for the main working tree, while other
+ working trees have `$GIT_DIR` equal to
+ `$GIT_COMMON_DIR/worktrees/<id>/`. The settings in the
+ `config.worktree` file will override settings from any other
+ config files.
++
+When enabling `extensions.worktreeConfig`, you must be careful to move
+certain values from the common config file to the main working tree's
+`config.worktree` file, if present:
++
+* `core.worktree` must be moved from `$GIT_COMMON_DIR/config` to
+ `$GIT_COMMON_DIR/config.worktree`.
+* If `core.bare` is true, then it must be moved from `$GIT_COMMON_DIR/config`
+ to `$GIT_COMMON_DIR/config.worktree`.
++
+It may also be beneficial to adjust the locations of `core.sparseCheckout`
+and `core.sparseCheckoutCone` depending on your desire for customizable
+sparse-checkout settings for each worktree. By default, the `git
+sparse-checkout` builtin enables `extensions.worktreeConfig`, assigns
+these config values on a per-worktree basis, and uses the
+`$GIT_DIR/info/sparse-checkout` file to specify the sparsity for each
+worktree independently. See linkgit:git-sparse-checkout[1] for more
+details.
++
+For historical reasons, `extensions.worktreeConfig` is respected
+regardless of the `core.repositoryFormatVersion` setting.

+sparse.expectFilesOutsideOfPatterns::
+ Typically with sparse checkouts, files not matching any
+ sparsity patterns are marked with a SKIP_WORKTREE bit in the
+ index and are missing from the working tree. Accordingly, Git
+ will ordinarily check whether files with the SKIP_WORKTREE bit
+ are in fact present in the working tree contrary to
+ expectations. If Git finds any, it marks those paths as
+ present by clearing the relevant SKIP_WORKTREE bits. This
+ option can be used to tell Git that such
+ present-despite-skipped files are expected and to stop
+ checking for them.
++
+The default is `false`, which allows Git to automatically recover
+from the list of files in the index and working tree falling out of
+sync.
++
+Set this to `true` if you are in a setup where some external factor
+relieves Git of the responsibility for maintaining the consistency
+between the presence of working tree files and sparsity patterns. For
+example, if you have a Git-aware virtual file system that has a robust
+mechanism for keeping the working tree and the sparsity patterns up to
+date based on access patterns.
++
+Regardless of this setting, Git does not check for
+present-despite-skipped files unless sparse checkout is enabled, so
+this config option has no effect unless `core.sparseCheckout` is
+`true`.

You can specify the information shown for each object by using a custom
`<format>`. The `<format>` is copied literally to stdout for each

NAME
----
-git-sparse-checkout - Initialize and modify the sparse-checkout
-configuration, which reduces the checkout to a set of paths
-given by a list of patterns.
+git-sparse-checkout - Reduce your working tree to a subset of tracked files
SYNOPSIS
DESCRIPTION
-----------
-Initialize and modify the sparse-checkout configuration, which reduces
-the checkout to a set of paths given by a list of patterns.
+This command is used to create sparse checkouts, which means that it
+changes the working tree from having all tracked files present, to only
+have a subset of them. It can also switch which subset of files are
+present, or undo and go back to having all tracked files present in the
+working copy.
+
+The subset of files is chosen by providing a list of directories in
+cone mode (which is recommended), or by providing a list of patterns
+in non-cone mode.
+
+When in a sparse-checkout, other Git commands behave a bit differently.
+For example, switching branches will not update paths outside the
+sparse-checkout directories/patterns, and `git commit -a` will not record
+paths outside the sparse-checkout directories/patterns as deleted.
THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR, AND THE BEHAVIOR OF OTHER
COMMANDS IN THE PRESENCE OF SPARSE-CHECKOUTS, WILL LIKELY CHANGE IN

+ and write a set of patterns to the sparse-checkout file from the
list of arguments following the 'set' subcommand. Update the
working directory to match the new patterns.
+
-When the `--stdin` option is provided, the patterns are read from
-standard in as a newline-delimited list instead of from the arguments.
+To ensure that adjusting the sparse-checkout settings within a worktree

-the skip-worktree bit is set, then the file is ignored in the working

EXAMPLES
--------
SKIP-WORKTREE BIT
-----------------
-Skip-worktree bit can be defined in one (long) sentence: When reading
-an entry, if it is marked as skip-worktree, then Git pretends its
-working directory version is up to date and read the index version
-instead.
-
-To elaborate, "reading" means checking for file existence, reading
-file attributes or file content. The working directory version may be
-present or absent. If present, its content may match against the index
-version or not. Writing is not affected by this bit, content safety
-is still first priority. Note that Git _can_ update working directory
-file, that is marked skip-worktree, if it is safe to do so (i.e.
-working directory version matches index version)
+Skip-worktree bit can be defined in one (long) sentence: Tell git to
+avoid writing the file to the working directory when reasonably
+possible, and treat the file as unchanged when it is not
+present in the working directory.
+
+Note that not all git commands will pay attention to this bit, and
+some only partially support it.
+
+The update-index flags and the read-tree capabilities relating to the
+skip-worktree bit predated the introduction of the
+linkgit:git-sparse-checkout[1] command, which provides a much easier
+way to configure and handle the skip-worktree bits. If you want to
+reduce your working tree to only deal with a subset of the files in
+the repository, we strongly encourage the use of
+linkgit:git-sparse-checkout[1] in preference to the low-level
+update-index and read-tree primitives.
+
+The primary purpose of the skip-worktree bit is to enable sparse
+checkouts, i.e. to have working directories with only a subset of
+paths present. When the skip-worktree bit is set, Git commands (such
+as `switch`, `pull`, `merge`) will avoid writing these files.
+However, these commands will sometimes write these files anyway in
+important cases such as conflicts during a merge or rebase. Git
+commands will also avoid treating the lack of such files as an
+intentional deletion; for example `git add -u` will not not stage a
+deletion for these files and `git commit -a` will not make a commit
+deleting them either.
Although this bit looks similar to assume-unchanged bit, its goal is
-different from assume-unchanged bit's. Skip-worktree also takes
-precedence over assume-unchanged bit when both are set.
+different. The assume-unchanged bit is for leaving the file in the
+working tree but having Git omit checking it for changes and presuming
+that the file has not been changed (though if it can determine without
+stat'ing the file that it has changed, it is free to record the
+changes). skip-worktree tells Git to ignore the absence of the file,
+avoid updating it when possible with commands that normally update
+much of the working directory (e.g. `checkout`, `switch`, `pull`,
+etc.), and not have its absence be recorded in commits. Note that in
+sparse checkouts (setup by `git sparse-checkout` or by configuring
+core.sparseCheckout to true), if a file is marked as skip-worktree in
+the index but is found in the working tree, Git will clear the
+skip-worktree bit for that file.
SPLIT INDEX
-----------
A git repository can support multiple working trees, allowing you to check
out more than one branch at a time. With `git worktree add` a new working
-tree is associated with the repository. This new working tree is called a
-"linked working tree" as opposed to the "main working tree" prepared by
-linkgit:git-init[1] or linkgit:git-clone[1].
-A repository has one main working tree (if it's not a
-bare repository) and zero or more linked working trees. When you are done
-with a linked working tree, remove it with `git worktree remove`.

+that differentiates that working tree from others in the same repository.
+The working tree, along with this metadata, is called a "worktree".

In its simplest form, `git worktree add <path>` automatically creates a
new branch whose name is the final component of `<path>`, which is
convenient if you plan to work on a new topic. For instance, `git
worktree add ../hotfix` creates new branch `hotfix` and checks it out at
-path `../hotfix`. To instead work on an existing branch in a new working
-tree, use `git worktree add <path> <branch>`. On the other hand, if you
-just plan to make some experimental changes or do testing without
-disturbing existing development, it is often convenient to create a
-'throwaway' working tree not associated with any branch. For instance,
-`git worktree add -d <path>` creates a new working tree with a detached
-`HEAD` at the same commit as the current branch.

If a working tree is deleted without using `git worktree remove`, then
its associated administrative files, which reside in the repository
(see "DETAILS" below), will eventually be removed automatically (see
`gc.worktreePruneExpire` in linkgit:git-config[1]), or you can run
-`git worktree prune` in the main or any linked working tree to
-clean up any stale administrative files.

-If a linked working tree is stored on a portable device or network share

REFS
----
-In multiple working trees, some refs may be shared between all working
-trees and some refs are local. One example is `HEAD` which is different for each
-working tree. This section is about the sharing rules and how to access
-refs of one working tree from another.
-
-In general, all pseudo refs are per working tree and all refs starting
-with `refs/` are shared. Pseudo refs are ones like `HEAD` which are
-directly under `$GIT_DIR` instead of inside `$GIT_DIR/refs`. There are
-exceptions, however: refs inside `refs/bisect` and `refs/worktree` are not
-shared.
-
-Refs that are per working tree can still be accessed from another
-working tree via two special paths, `main-worktree` and `worktrees`. The
-former gives access to per-working tree refs of the main working tree,
-while the latter to all linked working trees.

arguments. Here are the rules:
+ * Options come first and then args.
+ A subcommand may take dashed options (which may take their own
+ arguments, e.g. "--max-parents 2") and arguments. You SHOULD
+ give dashed options first and then arguments. Some commands may

+ arguments (which may make the command ambiguous), but you should

+ these ambiguity by enforcing the "options then args" rule).
+
* Revisions come first and then paths.
E.g. in `git diff v1.0 v2.0 arch/x86 include/asm-x86`,
`v1.0` and `v2.0` are revisions and `arch/x86` and `include/asm-x86`

other words, write `git foo -oArg` instead of `git foo -o Arg` for short
options, and `git foo --long-opt=Arg` instead of `git foo --long-opt Arg`
for long options. An option that takes optional option-argument must be
written in the 'stuck' form.

not ambiguous with a name of a file in the work tree. E.g. do not write

if you happen to have a file called `HEAD` in the work tree.
- * many commands allow a long option `--option` to be abbreviated

only to their unique prefix (e.g. if there is no other option
