Julia Lawall noticed that in linux-next repository the commit object
60d5c9f5 (shown with the default abbreviation width baked into "git
blame") in output from
$ git blame -L 3675,3675 60d5c9f5b -- \
drivers/staging/brcm80211/brcmfmac/wl_iw.c
is no longer unique in the repository, which results in "short SHA1
60d5c9f5 is ambiguous".
Compute the minimum abbreviation width that ensures uniqueness when
the user did not specify the --abbrev option to avoid this.

Only "diff --no-index -" does. Bolting the logic into the low-level
function diff_populate_filespec() was a layering violation from day
one. Move populate_from_stdin() function out of the generic diff.c
to its only user, diff-index.c.
Also make sure "-" from the command line stays a special token "read
from the standard input", even if we later decide to sanitize the
result from prefix_filename() function in a few obvious ways,
e.g. removing unnecessary "./" prefix, duplicated slashes "//" in
the middle, etc.

Regardless of where in the directory hierarchy you are, "-" on the
command line means the standard input. The old code knew too much
about how the low level machinery uses paths to read from the
working tree and did not bother to have the same check for "-" when
the command is run from the top-level.
Unify the codepaths for subdirectory case and toplevel case into one
and make it clearer.

"git diff --no-index" takes exactly two paths, not pathspecs, and
has its own way queue_diff() to populate the diff_queue. Do not
call diff_tree_setup_paths(), pretending as it takes pathspecs.

Split a rather heavy-ish "git completion" script out to create a
separate "git prompting" script, to help lazy-autoloading of the
completion part while making prompting part always available.
Teach "git submodule" deal with nested submodule structure where a
module is contained within a module whose origin is specified as a
relative URL to its superproject's origin.
When "--simplify-merges/by-decoration" is given together with
"--first-parent" to "git log", the combination of these options
makes the simplification logic to use in-core commit objects that
haven't been examined for relevance, either producing incorrect
result or taking too long to produce any output. Teach the
simplification logic to ignore commits that the first-parent
traversal logic ignored when both are in effect to work around the
issue.
"git add" allows adding a regular file to the path where a submodule
used to exist, but "git update-index" does not allow an equivalent
operation to Porcelain writers.
Attempt to optimize matching with an exclude pattern with a deep
directory hierarchy by taking the part that specifies leading path
without wildcard literally.
Setting this to a URL prefix instead of a path to a local directory allows
git-help --web to work even when HTML docs aren't locally installed, by
pointing the browser at a copy accessible on the web. For example,
[help]
format = html
htmlpath = http://git-scm.com/docs
will use the publicly available documentation on the git homepage.

The construct used to get the return code was flawed, in that
errors in the &&-chain before the semicolon were not caught. Use
the standard test_expect_code instead.
Set PATH in a subshell instead of relying on the bashism of
setting it just for a single command.
And fix the grep line so it doesn't worry about grep segfaults,

The original t9800 test code has a mix of assorted topics, some
of which are big enough to deserve their own homes.
Interdependencies between the topics make it confusing when
trying to study one in isolation. And it takes so long to run
that debugging an individual test is difficult.
Split out three big chunks of tests into their own files:
t9812-git-p4-wildcards.sh gets the 8 p4 wildcard tests
t9813-git-p4-preserve-users.sh gets the 4 --preserve-user tests
t9814-git-p4-rename.sh gets the 2 copy and rename tests
Test 9800 execution time drops from 29 sec to 9 sec. The
sequential time to run all tests is a slower due to the three
extra p4d startup/shutdown sequences, but the overall parallel
execution time is about the same, at 52 sec.

The p4 program is finicky about making sure the recorded client Root
matches the current working directory. The way it discovers the latter
seems to be to inspect shell variable $PWD. This could involve symlinks,
that while leading to the same place as the client Root, look different,
and cause p4 to fail.
Resolve all client paths using "test-path-utils real_path $path". This
removes ".." and resolves all symlinks.
Discovered while running with --root=/dev/shm, which is a link to
/run/shm.

Running tests at high parallelism on a slow machine, 5 sec is
not enough to wait for p4d to start. Change it to 5 minutes,

around. If not, quit waiting for it immediately.

A path containing a space must be quoted when used as an
argument to either the copy or rename commands (because
unlike other commands, the path is not the final thing on
the line for those commands).
Commit 6280dfdc3b (fast-export: quote paths in output,
2011-08-05) previously attempted to fix fast-export's
quoting by passing all paths through quote_c_style().
However, that function does not consider the space to be a
character which requires quoting, so let's special-case the
space inside print_path(). This will cause space-containing
paths to also be quoted in other commands where such quoting
is not strictly necessary, but it does not hurt to do so.
The test from 6280dfdc3b did not detect this because, while
it does introduce renames in the export stream, it does not
actually turn on rename detection, so they were presented as
pairs of deletions/adds. Using "-M" reveals the bug.

Allow --root to be specified to rebase -i without --onto, making it
possible to edit and re-order all commits right back to the root(s).
If there is a conflict to be resolved when applying the first change,
the user will expect a sane index and working tree to get sensible
behaviour from git-diff and friends, so create a sentinel commit with an
empty tree to rebase onto. Automatically squash the sentinel with any
commits rebased directly onto it, so they end up as root commits in
their own right and retain their authorship and commit message.
Implicitly use rebase -i for non-interactive rebase of --root without
an --onto argument now that rebase -i can correctly do this.

The Cygwin implementation of pread() is not thread-safe since, just
like the emulation provided by compat/pread.c, it uses a sequence of
seek-read-seek calls. In order to avoid failues due to thread-safety
issues, commit b038a61 disables threading when NO_PREAD is defined.
(ie when using the emulation code in compat/pread.c).
We introduce a new build variable, NO_THREAD_SAFE_PREAD, which allows
use to disable the threaded index-pack code on cygwin, in addition to
the above NO_PREAD case.

Since 5e835ca (rebase: do not munge commit log message, 2008-04-16),
'git am --rebasing' no longer gets the commit log message from the
patch, but reads it from the commit identified by the "From " header
line. From 43c2325 (am: use get_author_ident_from_commit instead of
mailinfo when rebasing, 2010-06-16), it also gets the author name,
email and date from the commit. Now that the final part of the patch
-- the patch body itself -- is also read from the commit, there is no
longer a need to call 'git mailinfo' to extract any of these parts
while --rebasing.

Rebasing a commit that contains a diff in the commit message results
in a failure with output such as
First, rewinding head to replay your work on top of it...

fatal: sha1 information is lacking or useless
(app/controllers/settings_controller.rb).
Repository lacks necessary blobs to fall back on 3-way merge.
Cannot fall back to three-way merge.
Patch failed at 0001 My cool patch.
The reason is that 'git rebase' without -p/-i/-m internally calls 'git
format-patch' and pipes the output to 'git am --rebasing', which has
no way of knowing what is a real patch and what is a commit message
that contains a patch.
Make 'git am' while in --rebasing mode get the patch body from the
commit object instead of extracting it from the mailbox.

Just like
git rebase --onto newbase upstream branch error
displays the usage message, so should clearly
git rebase --onto newbase --root branch error
, but it doesn't. Instead, it ignores both "branch" and "error" and
rebases the current HEAD. This is because we try to match the number
of remainging arguments "$#", which fails to match "1" argument and
matches the "*" that really should have been a "0".
Make sure we display usage information when too many arguments are
given. Also fail-fast in case of similar bugs in the future by
matching on exactly 0 arguments and failing on unknown numbers.
