That doesn't really cut the mustard, IMO.

If a `D' flag was off the window, you won't even
know whether that file was deleted, so you won't
know whether you want to undo.  At best, you'll
see a message telling you how many files were
deleted.

Plus, just what does undo do?  Will a user be
assured that _all_ deletions were undone?  Undo
does things in packets.  A user can easily worry
that only some of the deletions were undone.

Undo is no substitute for prompting for confirmation, IMO.
