tag: disallow tagging the working directory
It's kinda silly, but a clear error message is better than a stacktrace about
subscripting `None` when trying to generate the default commit message. I'm
surprised that `.revsingle(..).node()` returns None instead of `nodemod.wdirid`,
but now there's a test to catch if this changes.
