Currently fast-import/export cannot be used for
repositories with submodules. This patch extends
the relevant programs to make them correctly
process gitlinks.
Links can be represented by two forms of the
Modify command:
M 160000 SHA1 some/path
which sets the link target explicitly, or
M 160000 :mark some/path
where the mark refers to a commit. The latter
form can be used by importing tools to build
all submodules simultaneously in one physical
repository, and then simply fetch them apart.

The git-merge documentation's "HOW MERGE WORKS" section is confusingly
composed and actually omits the most interesting part, the merging of
the arguments into HEAD itself, surprisingly not actually mentioning
the fast-forward merge anywhere.
This patch replaces the "[NOTE]" screenful of highly technical details
by a single sentence summing up the interesting information, and instead
explains how are the arguments compared with HEAD and the three possible
inclusion states that are named "Already up-to-date", "Fast-forward"
and "True merge". It also makes it clear that the rest of the section
talks only about the true merge situation, and slightly expands the
talk on solving conflicts.
Junio initiated the removal of the Note screenful altogether and
offered many stylistical fixes.

zlib_compression_level is the compression level used for git's object store.
It's 1 by default, which is the fastest setting. This variable is also used
as the default compression level for ZIP archives created by git archive.
For archives, however, zlib's own default of 6 is more appropriate, as it's
favouring small size over speed -- archive creation is not that performance
critical most of the time.
This patch makes git archive independent from git's internal compression
level setting. It affects invocations of git archive without explicitly
specified compression level option, only.

This patch explains more carefully that `.gitignore` concerns only
untracked files and refers the reader to
git update-index --assume-unchanged
in the need of ignoring uncommitted changes in already tracked files.
The description of this option is lifted to a more "porcelainish"
level and explains the caveats of this usecase.
Whether feasible or not, I believe adding this functionality to
the porcelain is out of the scope of this patch. (And I personally
think that referring to the plumbing in the case of such a special
usage is fine.)
This is currently probably one of the top FAQs at #git and the
--assume-unchanged switch is not widely known; gitignore(5) is the first
place where people are likely to look for it.

This patch rewrites the general description yet again, first clarifying
the high-level concept, mentioning the difference to remotes and using
the subtree merge strategy, then getting to the details about tree
entries and .gitmodules file.
The patch also makes few smallar grammar fixups within the rest of the
description and clarifies how does 'init' relate to 'update --init'.

When hold_locked_index() is called with a relative git_dir and you are
outside the work tree, the lock file become relative to the current
directory. So when later setup_work_tree() change the current directory
it breaks lock file path and commit_locked_index() fails.

lock file relative to the working tree as it should be and add a test

The original code relied on an insane definition of skip_prefix() that
returned an empty string for a NULL input and returned the original if the
given "prefix" is not a prefix at all (it would have been justifiable if
it were called "come_up_with_a_short_name_to_report_ref()" or something,
though). In any case, when we replaced it with a more saner definition of
the function whose behaviour is true to its name, its callers needed to be
adjusted but the conversion missed one call site.
This introduces a helper function "abbrev_ref()" whose purpose is to get a
full refname and its possible prefix and to strip the prefix part if it
matches, or refname itself in full if it doesn't. This makes the callers
easier to read again.

This changes the message rerere issues after reusing previous conflict
resolution from "Resolved" to "Staged" when autoupdate option is in
effect.
It is envisioned that in practice, some auto resolitions are trickier and
iffier than others, and we would want to add a feature to mark individual
resolutions as "this is ok to autoupdate" or "do not autoupdate the result
using this resolution even when rerere.autoupdate is in effect" in the
future. When that happens, these messages will make the distinction
clearer.

The message length depends on the length of the branch name. In my case,
the branch name "origin/add-chickens2" put the first line of the "your
branch has diverged" message over 80 characters, which triggered "less -FS"
to not exit automatically as expected.
This patch rewords the messages to make the lines generally shorter, so
that you'd need a significantly longer branch name to trigger the problem.

If the repo is empty, it is obvious that there are no common commits
when fetching from _anywhere_.
So there is no use in saying it in that case, and it can even be
