Add support for an info version of the user manual
These patches use docbook2x in order to create an info version of the

touched, so you need to explicitly say
make info
sudo make install-info
to get git.info created and installed. If the info target directory
does not already contain a "dir" file, no directory entry is created.
This facilitates $(DESTDIR)-based installations. The same could be
achieved with
sudo make INSTALL_INFO=: install-info

perl is used for patching up sub-par file and directory information in
the Texinfo file. It would be cleaner to place the respective info
straight into user-manual.txt or the conversion configurations, but I

the bundle records that it requires v2.6.20^0 commit (correct)

When you have tons and tons of files in your repository, but there are
only small differences in the branches (maybe just a couple of files
changed), the biggest cost of the branch switching was actually just the
index calculations.
This fixes it (timings for switching between the "testing" and "master"

- you replace it with a "merge conflict" entry (ie a non-stage-0 entry)

Optimize "diff --cached" performance.
The read_tree() function is called only from the call chain to
run "git diff --cached" (this includes the internal call made by
git-runstatus to run_diff_index()). The function vacates stage
without any funky "merge" magic. The caller then goes and
compares stage #1 entries from the tree with stage #0 entries
from the original index.
When adding the cache entries this way, it used the general
purpose add_cache_entry(). This function looks for an existing
entry to replace or if there is none to find where to insert the
new entry, resolves D/F conflict and all the other things.
For the purpose of reading entries into an empty stage, none of
that processing is needed. We can instead append everything and
then sort the result at the end.
This commit changes read_tree() to first make sure that there is
no existing cache entries at specified stage, and if that is the
case, it runs add_cache_entry() with ADD_CACHE_JUST_APPEND flag
(new), and then sort the resulting cache using qsort().
This new flag tells add_cache_entry() to omit all the checks
such as "Does this path already exist? Does adding this path
remove other existing entries because it turns a directory to a
file?" and instead append the given cache entry straight at the
end of the active cache. The caller of course is expected to
sort the resulting cache at the end before using the result.

For various reasons we don't depend on the underlying OS groups

Users can be made a member of one or more groups by setting the
user.memberOf property within the "users/$who.acl" file:
This will cause the hook to also parse the "groups/$groupname.acl"
file for each value of user.memberOf, and merge any allow rules
that match the current repository with the user's own private rules
(if they had any).
Since some rules are basically the same but may have a component
differ based on the individual user, any user.* key may be inserted

unpack-trees.c: assume submodules are clean during check-out
Sven originally raised this issue:
If you have a submodule checked out and you go back (or
forward) to a revision of the supermodule that contains a
different revision of the submodule and then switch to
another revision, it will complain that the submodule is not
uptodate, because git simply didn't update the submodule in
the first move.
The current policy is to consider it is perfectly normal that
checked-out submodule is out-of-sync wrt the supermodule index.
At least until we introduce a superproject repository
configuration option that says "in this repository, I do care
about this submodule and at any time I move around in the
superproject, recursively check out the submodule to match", it
is a reasonable policy, as we currently do not recursively
checkout the submodules at all. The most extreme case of this
policy is that the superproject index knows about the submodule
but the subdirectory does not even have to be checked out.
The function verify_uptodate(), called during the two-way merge
aka branch switching, is about "make sure the filesystem entity
that corresponds to this cache entry is up to date, lest we lose
the local modifications". As we explicitly allow submodule
checkout to drift from the supermodule index entry, the check
should say "Ok, for submodules, not matching is the norm" for
now.
Later when we have the ability to mark "I care about this
submodule to be always in sync with the superproject" (thereby
implementing automatic recursive checkout and perhaps diff,
among other things), we should check if the submodule in
question is marked as such and perform the current test.

my day-job repositories can only be accessed via magic supplied
through the wonderous hack that is GIT_SSH.
Advertising it alongside other "low level magic" such as GIT_PAGER
and GIT_MERGE_VERBOSITY will certainly help others who need to
spread their own pixie dust to make things work.

If git_feed is provided a file name, it ought to show only the history

gitweb: do not choke on recursive symlink
If somebody used to advertise his repository that physically
resides at /pub/lic.git/ as:
git://git.example.com/pub/lic.git/
but now wants to use --base-path to allow:
git://git.example.com/lic.git/
she can start git-daemon with --base-path option, like this:
git-daemon --base-path=/pub --export-all
During the transition, however, she would also want to allow
older URL as well. One natural way to achieve that is to create
a symlink:
ln -s /pub /pub/pub
so that a request to git://git.example.com/pub/lic.git/ is first
translated by --base-path to a request to /pub/pub/lic.git/
which goes to /pub/lic.git, thanks to the symlink.
So far so good.
However, gitweb chokes if there is such a symlink (File::Find
barfs with "/pub/pub is a recursive symbolic link"). Make the
code ignore such a symlink.

git-clone: aggressively optimize local clone behaviour.
This changes the behaviour of cloning from a repository on the
local machine, by defaulting to "-l" (use hardlinks to share
files under .git/objects) and making "-l" a no-op. A new
option, --no-hardlinks, is also added to cause file-level copy
of files under .git/objects while still avoiding the normal
"pack to pipe, then receive and index pack" network transfer
overhead. The old behaviour of local cloning without -l nor -s
is availble by specifying the source repository with the newly
introduced file:///path/to/repo.git/ syntax (i.e. "same as
network" cloning).
* With --no-hardlinks (i.e. have all .git/objects/ copied via
cpio) would not catch the source repository corruption, and
also risks corrupted recipient repository if an
alpha-particle hits memory cell while indexing and resolving
deltas. As long as the recipient is created uncorrupted, you
have a good back-up.
* same-as-network is expensive, but it would catch the breakage
of the source repository. It still risks corrupted recipient
repository due to hardware failure. As long as the recipient
is created uncorrupted, you have a good back-up.
* The new default on the same filesystem, as long as the source
repository is healthy, it is very likely that the recipient
would be, too. Also it is very cheap. You do not get any
back-up benefit, though.
None of the method is resilient against the source repository
corruption, so let's discount that from the comparison. Then
the difference with and without --no-hardlinks matters primarily
if you value the back-up benefit or not. If you want to use the
cloned repository as a back-up, then it is cheaper to do a clone
with --no-hardlinks and two git-fsck (source before clone,
recipient after clone) than same-as-network clone, especially as
you are likely to do a git-fsck on the recipient if you are so
paranoid anyway.
Which leads me to believe that being able to use file:/// is
probably a good idea, if only for testability, but probably of
little practical value. We default to hardlinked clone for
everyday use, and paranoids can use --no-hardlinks as a way to
make a back-up.
When calling "git rebase -i <upstream> <branch>", git should switch
to <branch> first. This worked before, but I broke it by my
"Shut git rebase -i up" patch.
Fix that, and add a test to make sure that it does not break again.

git-sh-setup.sh: make GIT_EDITOR/core.editor/VISUAL/EDITOR accept commands
The previous code only allowed specifying a single executable rather
than a complete command like "emacsclient --alternate-editor vi" in
those variables. Since VISUAL/EDITOR appear to be traditionally
passed to a shell for interpretation (as corroborated with "less",
"mail" and "mailx", while the really ancient "more" indeed allows only
an executable name), the shell function git_editor has been amended
appropriately.
"eval" is employed to have quotes and similar interpreted _after_
expansion, so that specifying
EDITOR='"/home/dak/My Commands/notepad.exe"'
can be used for actually using commands with blanks.
Instead of passing just the first argument of git_editor on, we pass
all of them (so that +lineno might be employed at a later point of
time, or so that multiple files may be edited when appropriate).
Strictly speaking, there is a change in behavior: when
git config core.editor
returns a valid but empty string, the fallbacks are still searched.
This is more consistent, and the old code was problematic with regard
to multiple blanks. Putting in additional quotes might have worked,
but quotes inside of command substitution inside of quotes is nasty
enough to not reliably work the same across "Bourne shells".

The old version of work-tree support was an unholy mess, barely readable,
and not to the point.
For example, why do you have to provide a worktree, when it is not used?
As in "git status". Now it works.
Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?
IOW it is allowed to call
$ git --git-dir=../ --work-tree=. bla
when you really want to. In this case, you are both in the git directory
and in the working tree. So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.
Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.
The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:
--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.
In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir. This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.

since now all old paths will fail miserably.
So I added this --base-path-relaxed option, that will make git-daemon
try the absolute path without prefixing --base-path before giving up.
With this in place and --base-path-relaxed added, both my new url of
