One of us is confused, possibly me. That's how Stefan and I meant it
should work, too - that's what we mean by "uncommit".  Maybe rollback
worked that way at one time, but the RCS code before I deleted it said

            ;; Check out the most recent remaining version.  If it
            ;; fails, because the whole branch got deleted, do a
            ;; double-take and check out the version where the branch
            ;; started.

It was followed by co -u.  So either it never worked the way all three
of us think it should, or it did at one time but someone "corrected" it
to leave the master and workfile in what they thought was a more coherent
state. The latter seems not unlikely.
