[PATCH] Add --help to cogito 0.8

This patch adds -h and --help to all the cg- commands. It also moves the
detailed help printing from cg-help into cg-Xlib.

I created it because I could never remember if cg-log or cg-diff requires 
the -r before the revs.

Dear diary, on Mon, May 02, 2005 at 02:00:19AM CEST, I got a letter
where Alexander Beyn [off-list ref] told me that...

I created it because I could never remember if cg-log or cg-diff requires 
the -r before the revs.

Actually, would you people hate me / Cogito / Richard Stallman if I
added -r to cg-log and cg-mkpatch, for the sake of consistency?
Extending cg-log to work on individual files would be then obvious.


P.S.: Yes, I'm back and hope to catch with the rest of you during tomorrow.

I'd welcome this change, but I still like the ubiquitous -h and --help
on all the commands
