 - The --start-number handling introduced breakage in the normal
   code path.  It started numbering at 0 when not --numbered,
   for example.

 - When generating one file per patch, we needlessly added an
   extra blank line in front for second and subsequent files.

Since the "a..b c..d" syntax is interpreted as "b ^a d ^c" as other
range-ish commands, if you want to format a..b and then c..d and end
up with files consecutively numbered, the second run needs to be able
to tell the command what number to start from.

This does not imply --numbered (which gives [PATCH n/m] to the subject).

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.]

Handle the -S option when passed to git log such that only the
appropriate commits are displayed.  Also per Junio's comments, do
the same for "--diff-filter", so that it too can be used as an option
to git log.  By default no patch or diff information is displayed.

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.

I had to move the command line parsing around a little; setup_revisions()
could mistaken <dir> for a valid ref.

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...

Right now it split it into "builtin-log.c" for log-related commands
("log", "show" and "whatchanged"), and "builtin-help.c" for the
informational commands (usage printing and "help" and "version").

This just makes things easier to read, I find.
