You need "--verify". Otherwise git-rev-parse will think that you just have a strange filename or other random thing:

	prompt$ git-rev-parse 000^0
	000^0
	prompt$ git-rev-parse --verify 000^0
	fatal: Needed a single revision

Now, if the tag doesn't point to a commit, then the "^0" thing will fail. What you could use instead is

	git-rev-list --max-count=1 "$tag"

since git-rev-list will actually follow the tag. Of course, whether it does so correctly or not if the tagged object doesn't exist, I dunno. Testing needed.

Finally, you might just do it by hand
	type=$(git-cat-file -t "$obj") || exit
	if [ "$type" == "$tag" ]; then
		tagged=$(git-cat-file tag "$obj" |
			sed 's/object // ; q')
		git-rev-parse --verify "$tagged"
	fi
untested, of course.
