[PATCH] Add help details to git help command.

There's a patch at the bottom of this, so please look at that first before my reading my whining immediately below.

I'm having some troubles with git pull, so this is just an ordinary diff. Otherwise, I would have used the in-house diff command.

<troubles> patch: **** Only garbage was found in the patch input. </troubles> <more troubles> Tracked branch, applying changes... error: bad signature error: verify header failed read_cache: Invalid argument error: bad signature error: verify header failed error: bad signature error: verify header failed </more troubles>

Anyway, it's late, and I'm sure there is an easy fix to the above.

Here is a patch which provides the comment lines in the associated script files when the git help command is invoked with an argument thusly:

[steven@spc git-pasky-new]$ ./git help merge

 Merge a branch to the current tree.
 Copyright (c) Petr Baudis, 2005

 Takes a parameter identifying the branch to be merged.
 Optional "-b base_commit" parameter specifies the base for the
 merge. "-a" parameter may come first to tell git merge
 to check out the full tree to the merge tree.

 It creates a new ,,merge/ directory, which is git-controlled
 but has only the changed files checked out. You then have to
 examine it and then do git commit, which will also automatically
 bring your working tree up-to-date.

--------- This patch will provide the comment lines in the shell script associated with the command, cleaned up a bit for presentation.

BUGS: This will also print any comments in the entire file, which may
not be desired.  If a command name and shell script filename
do not follow the usual convention, this won't work, e.g. ci for commit.
