With this patch, if commit-id is passed a git tag, it will check to see

I'm not sure if this is the proper place to handle git tags, but it does
make things like "cg-diff -r v2.6.12-rc2:v2.6.12-rc3" work in the Linus
kernel tree. I've not noticed any problems this introduces, but I didn't 
do a thorough check.

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.
