[PATCH 13/15] name-rev: cleanup name_ref()

[SZEDER Gábor]

Earlier patches in this series moved a couple of conditions from the
recursive name_rev() function into its caller name_ref(), for no other
reason than to make eliminating the recursion a bit easier to follow.

Since the previous patch name_rev() is not recursive anymore, so let's
move all those conditions back into name_rev().
