[RFC] allow file list editing during cg-commit

[Eugene Surovegin <ebs@ebshome.net>]

Hi!

I just started playing with cogito and failed to find _easy_ way to
select which files will be committed and which won't. cg-commit seems
to support specifying file list in command line, but this isn't very
convenient when the list is big.

I tend to have many modified files in my repo, but commit them in
several different changeset.

I just made simple change to cg-commit which allows  editing file
list while editing log message; for example, if I have 30 files  ready
for commit, but want to commit only 29, I just remove this file
from "CG:" list.

Patch which demonstrates the idea follows. Please note, this is
just a quick hack, and I probably missed some cg-commit cases, when
such behavior is undesirable; also, I cheated a little to make
grepping easy :).
