When the user really wants to, "git fetch $there remotes/frotz/HEAD" would let her do so anyway, so this is not about safety or security; it merely is about confusion avoidance and discouraging meaningless usage. Specifically, it is _not_ about ambiguity avoidance. A name that would become ambiguous if we use the same rules table for both fetch and local rev-parse would be ambiguous locally at the remote side. So for the same reason as we added rule to allow "git fetch $there v1.0" instead of "git fetch $there tags/v1.0" in the previous commit, here is a bit longer rope for the users, which incidentally simplifies our code.
