3aed2fda6f builtin-fsck: fix off by one head count
According to the man page, if "git fsck" is passed one or more heads, it
should verify connectivity and validity of only objects reachable from the
heads it is passed.

However, since 5ac0a20 (Make builtin-fsck.c use parse_options.,
2007-10-15) the command behaved as if no heads were passed, when given
only one argument.

f0298cf1c6 revision walker: include a detached HEAD in --all
When HEAD is detached, --all should list it, too, logically, as a
detached HEAD is by definition a temporary, unnamed branch.

It is especially necessary to list it when garbage collecting, as
the detached HEAD would be trashed.

Noticed by Thomas Rast.

Note that this affects creating bundles with --all; I contend that it
is a good change to add the HEAD, so that cloning from such a bundle
will give you a current branch.  However, I had to fix t5701 as it
assumed that --all does not imply HEAD.

72183cb297 Fix gitdir detection when in subdir of gitdir
If the current working directory is a subdirectory of the gitdir (e.g.
<repo>/.git/refs/), then setup_git_directory_gently() will climb its
parent directories until it finds itself in a gitdir.  However, no
matter how many parent directories it climbs, it sets
'GIT_DIR_ENVIRONMENT' to ".", which is obviously wrong.

This behaviour affected at least 'git rev-parse --git-dir' and hence
caused some errors in bash completion (e.g. customized command prompt
when on a detached head and completion of refs).

To fix this, we set the absolute path of the found gitdir instead.

5c38ea31f3 contrib: add 'git difftool' for launching common merge tools
'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'.

466ddf90c2 http-push: when making directories, have a trailing slash in the path name
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.

c002922adc expand --pretty=format color options
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.

5ef8d77a75 color: make it easier for non-config to parse color specs
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.

2454ac7b9f builtin-commit.c: do not remove COMMIT_EDITMSG
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.

ae98a0089f Move run_hook() from builtin-commit.c into run-command.c (libgit)
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.

since then "<foo" becomes a word (and "bar>" doesn't!) even though the

classes can't match a newline.  Of course newlines can still be

2b6a5417d7 color-words: take an optional regular expression describing words
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.

2e5d2003b2 color-words: change algorithm to allow for 0-character word boundaries
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.

944019c8b3 t3501: check that commits are actually done
The basic idea of t3501 is to check whether revert

But as there is no pure cherry-pick/revert test, it is
good to also check if commits are actually done in that
scenario.

a42577d4c8 bash-completion: Add comments to remind about required arguments
Add a few simple comments above commands that take arguments. These
comments are meant to remind developers of potential problems that
can occur when the script is sourced on systems with "set -u." Any
function which requires arguments really ought to be called with
explicit arguments given.

Also adds a #!bash to the top of bash completions so that editing
software can always identify that the file is of sh type.

50e126e185 bash-completion: Try bash completions before simple filetype
When a git completion is not found, a bash shell should try bash-type
completions first before going to standard filetype completions. This
patch adds "-o bashdefault" to the completion line. If that option is
not available, it uses the old method.

This behavior was inspired by Mercurial's bash completion script.

25a31f8140 bash-completion: Support running when set -u is enabled
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-}.
