[COGITO] cg-status in an empty repo spits out git-diff-index usage info

[Re-sending ..]

Hello Petr, git list,

A `cg-status` in an empty repo (i.e., straight after a `cg-init -I`)
spits out git-diff-index usage information, a la:

	[($) 09:03:42] beu@zippy ~/git/test
	> cg-status
	Heads:
	    >master
	    
	    usage: git-diff-index [-m] [--cached] [<common diff options>] <tree-ish> [<path>...]
	    common diff options:
	    [...]

which I'm guessing isn't expected behaviour ;)  `git status` does the
same, FWIW.  I'm having a look around to try and figure out why, and
will try to work up a patch to fix it, but in case I don't find the bug
(or feature ;), consider this a heads-up. :)

(And I've just used gitk for the first time, too, and I must say it's
one invaluable piece of software !  Kudos to it's creators :)

This is with latest cogito.git (b06f2a707963c8712f7a6bbd4b89bae758bcf92a,
though the 'bug' is also present in 0.15.1) with git 0.99.7d.

Best,
Elfyn
