Subject: Tentative built-in format-patch.

This only does --stdout right now.  To write into separate files
with pretty-printed filenames like the real thing does, it needs
a bit mroe work.

From: Johannes Schindelin <Johannes.Schindelin@gmx.de>
Date: Fri, 5 May 2006 01:16:40 +0200
Subject: Teach fmt-patch to write individual files.

When called with "--stdout", it still writes to standard output.

Notable differences to git-format-patch:

	- since fmt-patch uses the standardized logging machinery, it is
	  no longer "From nobody", but "From <commit_sha1>",

	- the empty lines before and after the "---" just before the
	  diffstat are no longer there,

	- git-format-patch outputs the commit_sha1 just before the first
	  diff, which fmt-patch does not,

	- the file names are no longer output to stdout, but to stderr
	  (since stdout is freopen()ed all the time), and

	- "git fmt-patch HEAD^" does not work as expected: it outputs
	  *all* commits reachable from HEAD^!

The last one is possibly a showstopper. At least I used to call that
command quite often...

Subject: fmt-patch: understand old <his> notation

When calling "git fmt-patch HEAD~5", you now get the same as if you would
have said "git fmt-patch HEAD~5..". This makes it easier for my fingers
which are so used to the old syntax.

Subject: fmt-patch: Support --attach

This patch touches a couple of files, because it adds options to print a
custom text just after the subject of a commit, and just after the
diffstat.

[jc: made "many dashes" used as the boundary leader into a single
 variable, to reduce the possibility of later tweaks to miscount the
 number of dashes to break it.]

-When -o is specified, output files are created in <dir>; otherwise

-When -n is specified, instead of "[PATCH] Subject", the first
