Better, but this still runs only in one window.  That's not the same as a
unified Emacs environment over *all* your windows, so that you can cut and
paste between them and so on.

Not true.  Gnu Emacs's UNDO can undo arbitrarily far back too; in addition,
it lets you define arbitrary UNDO boundaries and other good stuff.

The DM's UNDO function is pretty nice, except (a) you can't UNDO UNDOes
(which is a *serious* disadvantage), and (b) it doesn't leave your cursor
where you expect it to be, putting it instead at the beginning of the line
(which is a minor annoyance).
