log-tree: show_log: make commentary block delimiting reusable
In patches generated by git-format-patch, the area below the "---" line
following the commit message and before the actual 'diff' can be used
for commentary which the patch author wants to convey to readers of the
patch itself but not include in the commit message proper.
By default, the commentary area is empty, however, the --notes option
causes it to be populated with notes associated with the commit. In the
future, other options may be added which also insert content into the
commentary section.
To accommodate this, factor out the logic which delimits commentary
blocks from the commit message so that it can be re-used for upcoming
optional inserted content.

format-patch: add --interdiff option to embed diff in cover letter
When submitting a revised version of a patch series, it can be helpful
(to reviewers) to include a summary of changes since the previous
attempt in the form of an interdiff, however, doing so involves manually
copy/pasting the diff into the cover letter.
Add an --interdiff option to automate this process. The argument to

In ed32b788c06 (version --build-options: report commit, too, if
possible, 2017-12-15), we introduced code to let `git version
--build-options` report the current commit from which the binaries were
built, if any.
To prevent erroneous commits from being reported (e.g. when unpacking
Git's source code from a .tar.gz file into a subdirectory of a different
Git project, as e.g. git_osx_installer does), we painstakingly set
GIT_CEILING_DIRECTORIES when trying to determine the current commit.
Except that we got the quoting wrong, and that variable therefore does
not have the desired effect.
The issue is that the $(shell) is resolved before the output is stuffed
into the command-line with -DGIT_BUILT_FROM_COMMIT, and therefore is
*not* inside quotes. And thus backslashing the quotes is wrong, as the
quote gets literally inserted into the CEILING_DIRECTORIES variable.
Let's fix that quoting, and while at it, also suppress the unhelpful
message
fatal: not a git repository (or any of the parent directories): .git
that gets printed to stderr if no current commit could be determined,
and might scare the occasional developer who simply tries to build Git

the constants used by the implementation and specified by the format
document.
The commit data chunk uses the key "CDAT" in the file format, but was
previously documented to say "CGET".
The commit data chunk stores commit parents using two 32-bit fields that
typically store the integer position of the parent in the list of commit
ids within the commit-graph file. When a parent does not exist, we had
documented the value 0xffffffff, but implemented the value 0x70000000.

reduces the number of commits that we can store in the commit-graph.

branch: deprecate "-l" option
The "-l" option is short for "--create-reflog". This has
caused much confusion over the years. Most people expect it
to work as "--list", because that would match the other
"mode" options like -d/--delete and -m/--move, as well as
the similar -l/--list option of git-tag.
Adding to the confusion, using "-l" _appears_ to work as
"--list" in some cases:
$ git branch -l
* master
because the branch command defaults to listing (so even
trying to specify --list in the command above is redundant).
But that may bite the user later when they add a pattern,
like:
$ git branch -l foo
which does not return an empty list, but in fact creates a
new branch (with a reflog, naturally) called "foo".
It's also probably quite uncommon for people to actually use
"-l" to create a reflog. Since 0bee591869 (Enable reflogs by
default in any repository with a working directory.,
2006-12-14), this is the default in non-bare repositories.
So it's rather unfortunate that the feature squats on the
short-and-sweet "-l" (which was only added in 3a4b3f269c
(Create/delete branch ref logs., 2006-05-19), meaning there
were only 7 months where it was actually useful).
Let's deprecate "-l" in hopes of eventually re-purposing it
to "--list".
Note that we issue the warning only when we're not in list
mode. This means that people for whom it works as a happy
accident, namely:
$ git branch -l
master
won't see the warning at all. And when we eventually switch
to it meaning "--list", that will just continue to work.
We do the issue the warning for these important cases:
- when we are actually creating a branch, in case the user
really did mean it as "--create-reflog"
- when we are in some _other_ mode, like deletion. There
the "-l" is a noop for now, but it will eventually
conflict with any other mode request, and the user
should be told that this is changing.

t: switch "branch -l" to "branch --create-reflog"
In preparation for deprecating "-l", let's make sure we're
using the recommended option ourselves.
This patch just mechanically converts "branch -l" to "branch
--create-reflog". Note that with the exception of the
actual "--create-reflog" test, we could actually remove "-l"
entirely from most of these callers. That's because these
days core.logallrefupdates defaults to true in a non-bare
repository.
I've left them in place, though, since they serve to
document the expectation of the test, even if they are
technically noops.

t3200: unset core.logallrefupdates when testing reflog creation
This test checks that the "-l" option creates a reflog. But
in fact we'd create one even without it, since the default
in a non-bare repository is to do so. Let's unset the config
so we can be sure our "-l" option is kicking in.
Note that we can't do this with test_config, since that
would leave the variable unset after our test finishes,
confusing downstream tests (the helper is not not smart
enough to restore the previous value, and just always runs
test_unconfig).

grep.c: expose {,inverted} match column in match_line()
When calling match_line(), callers presently cannot determine the
relative offset of the match because match_line() discards the
'regmatch_t' that contains this information.
Instead, teach match_line() to take in two 'ssize_t's. Fill the first
with the offset of the match produced by the given expression. If
extended, fill the later with the offset of the match produced as if
--invert were given.
For instance, matching "--not -e x" on this line produces a columnar
offset of 0, (i.e., the whole line does not contain an x), but "--invert
--not -e -x" will fill the later ssize_t of the column containing an
"x", because this expression is semantically equivalent to "-e x".
To determine the column for the inverted and non-inverted case, do the
following:
- If matching an atom, the non-inverted column is as given from
match_one_pattern(), and the inverted column is unset.
- If matching a --not, the inverted column and non-inverted column
swap.
- If matching an --and, or --or, the non-inverted column is the
minimum of the two children.
Presently, the existing short-circuiting logic for AND and OR applies as
before. This will change in the following commit when we add options to
configure the --column flag. Taken together, this and the forthcoming
change will always yield the earlier column on a given line.
This patch will become useful when we later pick between the two new
results in order to display the column number of the first match on a
line with --column.

pack-bitmap: remove bitmap_git global variable
Remove the bitmap_git global variable. Instead, generate on demand an
instance of struct bitmap_index for code that needs to access it.
This allows us significant control over the lifetime of instances of
struct bitmap_index. In particular, packs can now be closed without
worrying if an unnecessarily long-lived "pack" field in struct
bitmap_index still points to it.
The bitmap API is also clearer in that we need to first obtain a struct
bitmap_index, then we use it.
This patch raises two potential issues: (1) memory for the struct
bitmap_index is allocated without being freed, and (2)
prepare_bitmap_git() and prepare_bitmap_walk() can reuse a previously
loaded bitmap. For (1), this will be dealt with in a subsequent patch in
this patch set that also deals with freeing the contents of the struct
bitmap_index (which were not freed previously, because they have global
scope). For (2), current bitmap users only load the bitmap once at most
(note that pack-objects can use bitmaps or write bitmaps, but not both
at the same time), so support for reuse has no effect - and future users
can pass around the struct bitmap_index * obtained if they need to do 2
or more things with the same bitmap.

sequencer: do not squash 'reword' commits when we hit conflicts
Ever since commit 18633e1a22 ("rebase -i: use the rebase--helper builtin",
2017-02-09), when a commit marked as 'reword' in an interactive rebase
has conflicts and fails to apply, when the rebase is resumed that commit
will be squashed into its parent with its commit message taken.
The issue can be understood better by looking at commit 56dc3ab04b
("sequencer (rebase -i): implement the 'edit' command", 2017-01-02), which
introduced error_with_patch() for the edit command. For the edit command,
it needs to stop the rebase whether or not the patch applies cleanly. If
the patch does apply cleanly, then when it resumes it knows it needs to
amend all changes into the previous commit. If it does not apply cleanly,
then the changes should not be amended. Thus, it passes !res (success of
applying the 'edit' commit) to error_with_patch() for the to_amend flag.
The problematic line of code actually came from commit 04efc8b57c
("sequencer (rebase -i): implement the 'reword' command", 2017-01-02).
Note that to get to this point in the code:
* !!res (i.e. patch application failed)
* item->command < TODO_SQUASH
* item->command != TODO_EDIT
* !is_fixup(item->command) [i.e. not squash or fixup]
So that means this can only be a failed patch application that is either a
pick, revert, or reword. We only need to amend HEAD when rewording the
root commit or a commit that has been fast-forwarded, for any of the other
cases we want a new commit, so we should not set the to_amend flag.
