671c9b7e31 Add cache preload facility
This can do the lstat() storm in parallel, giving potentially much
improved performance for cold-cache cases or things like NFS that have
weak metadata caching.

Just use "read_cache_preload()" instead of "read_cache()" to force an
optimistic preload of the index stat data.  The function takes a
pathspec as its argument, allowing us to preload only the relevant
portion of the index.

0b38227f28 commit: Fix stripping of patch in verbose mode.
When the "-v" option is given, we put diff of what is to be committed into
the commit template, and then strip it back out again after the user has
edited it.

We used to look for the diff by searching for the "diff --git a/"
header. With diff.mnemonicprefix set in the configuration, however, this
pattern does not match.  The pattern is loosened to cover this case.

Also, if the user puts their own diff in the message (e.g., as a sample
output), then we will accidentally trigger the pattern, removing part of
their output.

We can avoid doing this stripping altogether if the user didn't use "-v"
in the first place, so we know that any match we find will be a false
positive.

[jc: this fix was split out of a series originally meant for master.]

f285a2d7ed Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializer
Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

cf10f9fdd5 builtin-commit: use reduce_heads() only when appropriate
Since commit 6bb6b034 (builtin-commit: use commit_tree(), 2008-09-10),
builtin-commit performs a reduce_heads() unconditionally.  However,
it's not always needed, and in some cases even harmful.

reduce_heads() is not needed for the initial commit or for an
"ordinary" commit, because they don't have any or have only one
parent, respectively.

reduce_heads() must be avoided when 'git commit' is run after a 'git
merge --no-ff --no-commit', otherwise it will turn the
non-fast-forward merge into fast-forward.  For the same reason,
reduce_heads() must be avoided when amending such a merge commit.

To resolve this issue, 'git merge' will write info about whether
fast-forward is allowed or not to $GIT_DIR/MERGE_MODE.  Based on this
info, 'git commit' will only perform reduce_heads() when it's
committing a merge and fast-forward is enabled.

Also add test cases to ensure that non-fast-forward merges are
committed and amended properly.

c85db254d9 reformat informational commit message
When committing, we print a message like:

  Created [DETACHED commit] <hash> (<subject>) on <branch>

The most useful bit of information there (besides the
detached status, if it is present) is which branch you made
the commit on. However,  it is sometimes hard to see because
the subject dominates the line.

Instead, let's put the most useful information (detached
status and commit branch) on the far left, with the subject
(which is least likely to be interesting) on the far right.

We'll use brackets to offset the branch name so the line is
not mistaken for an error line of the form "program: some
sort of error". E.g.,:

  [jk/bikeshed] created bd8098f: "reformat informational commit message"

72c69ebc03 git commit: Reformat output somewhat
Previously, we used to print something along the lines of

	Created commit abc9056 on master: Snib the sprock

but that output was sometimes confusing, as many projects use
the "subsystem: message" style of commit subjects (just like
this commit message does). When such improvements are done on
topic-branches, it's not uncommon to name the topic-branch the
same as the subsystem, leading to output like this:

	Created commit abc9056 on i386: i386: Snib the sprock

which doesn't look very nice and can be highly confusing.
This patch alters the format so that the noise-word "commit"
is dropped except when it makes the output read better and
the commit subject is put inside parentheses. We also
emphasize the detached case so that users do not overlook it
in case the commit subject is long enough to extend to the
next line. The end result looks thusly:

	normal case
	Created abc9056 (i386: Snib the sprock) on i386

	detached head
	Created DETACHED commit abc9056 (i386: Snib the sprock)

While we're at it, we rename "initial commit" to "root-commit"
to align it with the argument to 'git log', producing this:

	initial commit
	Created root-commit abc9056 (i386: Snib the sprock) on i386

Documentation/gittutorial-2.txt is updated accordingly so that
new users recognize what they're looking at.

dbd0f5c769 Files given on the command line are relative to $cwd
When running "git commit -F file" and "git tag -F file" from a
subdirectory, we should take it as relative to the directory we started
from, not relative to the top-level directory.

This adds a helper function "parse_options_fix_filename()" to make it more
convenient to fix this class of issues.  Ideally, parse_options() should
support a new type of option, "OPT_FILENAME", to do this uniformly, but
this patch is meant to go to 'maint' to fix it minimally.

One thing to note is that value for "commit template file" that comes from
the command line is taken as relative to $cwd just like other parameters,
but when it comes from the configuration varilable 'commit.template', it
is taken as relative to the working tree root as before.  I think this
difference actually is sensible (not that I particularly think
commit.template itself is sensible).

fdc7c81111 Compact commit template message
We recently let the user know explicitly that an empty
commit message will abort the commit. However, this adds yet
another line to the template; let's rephrase and re-wrap so
that this fits back on two lines.

This patch also makes the "fatal: empty commit message?"
warning a bit less scary, since this is now a "feature"
instead of an error. However, we retain the non-zero exit
status to indicate to callers that nothing was committed.

e1645901ed builtin-commit.c: add -u as short name for --untracked-files
This makes the C code consistent with the documentation and the old shell
code.

d177cab048 Avoid some unnecessary lstat() calls
The commit sequence used to do

	if (file_exists(p->path))
		add_file_to_cache(p->path, 0);

where both "file_exists()" and "add_file_to_cache()" needed to do a
lstat() on the path to do their work.

This cuts down 'lstat()' calls for the partial commit case by two
for each path we know about (because we do this twice per path).

Just move the lstat() to the caller instead (that's all that
"file_exists()" really does), and pass the stat information down to the
add_to_cache() function.

This essentially makes 'add_to_index()' the core function that adds a path
to the index, getting the index pointer, the pathname and the stat
information as arguments. There are then shorthand helper functions that
use this core function:

 - 'add_to_cache()' is just 'add_to_index()' with the default index

 - 'add_file_to_cache/index()' is the same, but does the lstat() call
   itself, so you can pass just the pathname if you don't already have the
   stat information available.

So old users of the 'add_file_to_xyzzy()' are essentially left unchanged,
and this just exposes the more generic helper function that can take
existing stat information into account.
