rollback: only restore dirstate and branch when appropriate.
If the working dir parent was destroyed by rollback, then the old
behaviour is perfectly reasonable: restore dirstate, branch, and
bookmarks. That way the working dir moves back to an existing
changeset rather than becoming an orphan.
But if the working dir parent was unaffected -- say, you updated to an
older changeset and then did rollback -- then it's silly to restore
dirstate and branch. So don't do that. Leave the status of the working
dir alone. (But always restore bookmarks, because that file refers to
changeset IDs that may have been destroyed.)
