Rollback is used to undo the effects of one or more patches without actually
deleting them.  Instead, it creates a new patch reversing selected portions.
of those changes. Unlike obliterate and unrecord (which accomplish a similar
goal) rollback is perfectly safe, since it leaves in the repository a record
of its changes.
