For some reason I've done a "git grep" twice with no pattern, which is
really irritating, since it just grep everything. If I actually wanted
that, I could do "git grep ^" or something.
So add a "usage" message if the pattern is empty.

Updates to fix the nits found during the list discussion.
- Lose PATH_TO_MAN; just rely on execlp() to find whereever the
"man" command is installed.
- Do not randomly chdir(), but concatenate to the current
working directory only if the given path is not absolute.
- Lose use of glob(); read from exec_path and do sorting
ourselves -- it is not that much more work.

python 2.2.1 is perfectly capable of executing git-merge-recursive,
provided that it finds heapq and sets. All you have to do is to steal
heapq.py and sets.py from python 2.3 or newer, and drop them in your
GIT_PYTHON_PATH.

This patch provides a C implementation of the 'git' program and
introduces support for putting the git-* commands in a directory
of their own. It also saves some time on executing those commands
in a tight loop and it prints the currently available git commands
in a nicely formatted list.
The location of the GIT_EXEC_PATH (name discussion's closed, thank gods)
can be obtained by running
git --exec-path
which will hopefully give porcelainistas ample time to adapt their
heavy-duty loops to call the core programs directly and thus save
the extra fork() / execve() overhead, although that's not really
necessary any more.
The --exec-path value is prepended to $PATH, so the git-* programs
should Just Work without ever requiring any changes to how they call
other programs in the suite.
Some timing values for 10000 invocations of git-var >&/dev/null:
git.sh: 24.194s
git.c: 9.044s
git-var: 7.377s
The git-<tab><tab> behaviour can, along with the someday-to-be-deprecated
git-<command> form of invocation, be indefinitely retained by adding
the following line to one's .bash_profile or equivalent:
PATH=$PATH:$(git --exec-path)
Experimental libraries can be used by either setting the environment variable
GIT_EXEC_PATH, or by using
git --exec-path=/some/experimental/exec-path
Relative paths are properly grok'ed as exec-path values.

A while ago, a rename-detection limit logic was implemented as a
response to this thread:
http://marc.theaimsgroup.com/?l=git&m=112413080630175
where gitweb was found to be using a lot of time and memory to
detect renames on huge commits. git-diff family takes -l<num>
flag, and if the number of paths that are rename destination
candidates (i.e. new paths with -M, or modified paths with -C)
are larger than that number, skips rename/copy detection even
when -M or -C is specified on the command line.
This commit makes the rename detection limit easier to use. You
can have:
[diff]
renamelimit = 30
in your .git/config file to specify the default rename detection
limit. You can override this from the command line; giving 0
means 'unlimited':
git diff -M -l0
We might want to change the default behaviour, when you do not
have the configuration, to limit it to say 20 paths or so. This
would also help the diffstat generation after a big 'git pull'.

Store pointers to referenced objects in a variable sized array instead
of linked list. This cuts down memory usage of utilities which use
object references; e.g., git-fsck-objects --full on the git.git
repository consumes about 2 MB of memory tracked by Massif instead of
7 MB before the change. Object refs are still the biggest consumer of
memory (57%), but the malloc overhead for a single block instead of a
linked list is substantially smaller.

This patch renames the tarball "git" rather than "git-core", and changes
the names of various packages from git-core-foo to git-foo. git-core is
still the true core package; an empty RPM package named "git" pulls in
ALL the git packages -- this makes updates work correctly, and allows
"yum install git" to do the obvious thing.
It also renames the git-(core-)tk package to gitk.

The -r flag means "rev-list order", i.e. just display the commits
in the order they come from git-rev-list.
The speedups include:
- don't process the whole commit line-by-line, only the header
- don't convert dates when reading the commits, rather do it when
needed
- don't do the $canv delete lines.$id in drawlines when drawing the
graph initially (it was taking a lot of the total time)
- cache the date conversion for each hour (more important with tk8.5,
since [clock format] is a lot slower in 8.5 than in 8.4).

This fixes git-rev-list so that when there are multiple branches, we still
sort the heads in proper approximate date order even when sorting the
output topologically.
This makes things like
gitk --all -d
work sanely and show the branches in date order (where "date order" is
obviously modified by the paren-child dependency requirements of the
topological sort).
The trivial fix is to just build the "work" list in date order rather than
inserting the new work entries at the beginning.
