Ahh, I forgot about that. Yes, indeed the command does not work
like other Git commands, which would just let generic revision parser
to accept an object name from anywhere. Probably it was a mistake,
because "git tag --verify $T" may find refs/tags/$T but that may not
necessarily mean "git checkout $T^0" would give you that exact
tree state, but it is too late to change now.

So yes, I agree with you that any validation-related thing needs to
start from names relative to refs/tags/, not from object names, to be
consistent.

Which is a bit sad, but I do not offhand think of a way to avoid it.
