Actually, the simplest way to handle this might be to just delete all
five of those tags during the conversion, and then I'll put them back
in the right places later when I add the other old-release tags.
That way we won't have any tags getting moved after the repository is
published.  (Or am I wrong about that being something to avoid?  But
in any case we want to gc the manufactured commits for Release_2_0_0
and Release_2_0.)
