Hmm. Just looking at this as a git user, I would have expected it to
take one or more hashes, separated by spaces. If only one, then it must
be a commit, and it is diffed against its parents. If more than one,
then each must be a tree-ish. So you could diff a commit against a tree
(or a tag against a commit, or...).

And I think it might even be easier to code. ;)
