I like this feature and it works on the Linus tree for me as well.
However, it fails on the cogito tree as follows:

mporter@beef:~/src/cogito$ cg-diff -r git-pasky-0.7:cogito-0.8
.git/objects/c8/3b95297c2a6336c2007548f909769e0862b509: No such file or directory

I haven't looked any further at it yet though.
