'git difftool' is a git command that allows you to compare and edit files
between revisions using common merge tools. 'git difftool' does what
'git mergetool' does but its use is for non-merge situations such as
when preparing commits or comparing changes against the index.
It uses the same configuration variables as 'git mergetool' and
provides the same command-line interface as 'git diff'.

Replace isspecial() by the new macro is_glob_special(), which is more,
well, specialized. The former included the NUL char in its character
class, while the letter only included characters that are special to
file name globbing.
The new name contains underscores because they enhance readability
considerably now that it's made up of three words. Renaming the
function is necessary to document its changed scope.

The function lock_remote() sends MKCOL requests to make leading
directories; However, if it does not put a forward slash '/' at the end of
the path, the server sends a 301 redirect.
By leaving the '/' in place, we can avoid this additional step.
Incidentally, at least one version of Curl (7.16.3) does not resend
credentials when it follows a 301 redirect, so this commit also fixes
a bug.

Currently, the only colors available to --pretty=format
users are red, green, and blue. Rather than expand it with a
few new colors, this patch makes the usual config color
syntax available, including more colors, backgrounds, and
attributes.
Because colors are no longer bounded to a single word (e.g.,
%Cred), this uses a more advanced syntax that features a
beginning and end delimiter (but the old syntax still
works). So you can now do:
git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even
git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'
if you want to relive the awesomeness of 4-color CGA.

We have very featureful color-parsing routines which are
used for color.diff.* and other options. Let's make it
easier to use those routines from other parts of the code.
This patch adds a color_parse_mem() helper function which
takes a length-bounded string instead of a NUL-terminated
one. While the helper is only a few lines long, it is nice
to abstract this out so that:
- callers don't forget to free() the temporary buffer
- right now, it is implemented in terms of color_parse().
But it would be more efficient to reverse this and
implement color_parse in terms of color_parse_mem.
This also changes the error string for an invalid color not
to mention the word "config", since it is not always
appropriate (and when it is, the context is obvious since
the offending config variable is given).
Finally, while we are in the area, we clean up the parameter
names in the declaration of color_parse; the var and value
parameters were reversed from the actual implementation.

git-commit tries to remove the file ./COMMIT_EDITMSG instead of
$GIT_DIR/COMMIT_EDITMSG after commit preparation (e.g. running
hooks, launching editor).
This behavior exists since f5bbc3225c "Port git commit to C".
Some test cases (e.g. t/t7502-commit.sh) rely on the existence of
$GIT_DIR/COMMIT_EDITMSG after committing and, I guess, many people
are used to it. So it is best not to remove it.
This patch just removes the removal of COMMIT_EDITMSG.

A function that runs a hook is used in several Git commands.
builtin-commit.c has the one that is most general for cases without
piping. The one in builtin-gc.c prints some useful warnings.
This patch moves a merged version of these variants into libgit and
lets the other builtins use this libified run_hook().
The run_hook() function used in receive-pack.c feeds the standard
input of the pre-receive or post-receive hooks. This function is
renamed to run_receive_hook() because the libified run_hook() cannot
handle this.

While at it, I removed the xstrdup() around the sha1_to_hex(...) calls

Make the --color-words splitting regular expression configurable via
the diff driver's 'wordregex' attribute. The user can then set the
driver on a file in .gitattributes. If a regex is given on the
command line, it overrides the driver's setting.
We also provide built-in regexes for the languages that already had
funcname patterns, and add an appropriate diff driver entry for C/++.
(The patterns are designed to run UTF-8 sequences into a single chunk
to make sure they remain readable.)

We silently truncate a match at the newline, which may lead to
unexpected behaviour, e.g., when matching "<[^>]*>" against
<foo
bar>
since then "<foo" becomes a word (and "bar>" doesn't!) even though the
regex said only angle-bracket-delimited things can be words.
To alleviate the problem slightly, use REG_NEWLINE so that negated
classes can't match a newline. Of course newlines can still be
matched explicitly.

In some applications, words are not delimited by white space. To
allow for that, you can specify a regular expression describing
what makes a word with
git diff --color-words='[A-Za-z0-9]+'
Note that words cannot contain newline characters.
As suggested by Thomas Rast, the words are the exact matches of the
regular expression.
Note that a regular expression beginning with a '^' will match only
a word at the beginning of the hunk, not a word at the beginning of
a line, and is probably not what you want.

Up until now, the color-words code assumed that word boundaries are
identical to white space characters.
Therefore, it could get away with a very simple scheme: it copied the
hunks, substituted newlines for each white space character, called
libxdiff with the processed text, and then identified the text to
output by the offsets (which agreed since the original text had the
same length).
This code was ugly, for a number of reasons:
- it was impossible to introduce 0-character word boundaries,
- we had to print everything word by word, and
- the code needed extra special handling of newlines in the removed part.
Fix all of these issues by processing the text such that
- we build word lists, separated by newlines,
- we remember the original offsets for every word, and
- after calling libxdiff on the wordlists, we parse the hunk headers, and
find the corresponding offsets, and then
- we print the removed/added parts in one go.
The pre and post samples in the test were provided by Santi Béjar.
Note that there is some strange special handling of hunk headers where
one line range is 0 due to POSIX: in this case, the start is one too
low. In other words a hunk header '@@ -1,0 +2 @@' actually means that
the line must be added after the _second_ line of the pre text, _not_
the first.

Under "set -u" semantics, it is an error to access undefined variables.
Some user environments may enable this setting in the interactive shell.
In any context where the completion functions access an undefined
variable, accessing a default empty string (aka "${1-}" instead of "$1")
is a reasonable way to code the function, as it silences the undefined
variable error while still supplying an empty string.
In this patch, functions that should always take an argument still use
$1. Functions that have optional arguments use ${1-}.
