I've been thinking about option parsing as well, and I think cogito 
could use a more "getopt-like" handling of options. "cg-log -cf"
or "cg-diff -rorigin" is just so much easier to type...

The attached patch implements that for cg-log and cg-diff, by means of 
two new helper functions in cg-Xlib. It also improves error-handling a bit.

How about it?
