Therefore for us the redo.el package is very important so either
redo.el should work after this internal undo-changes or - and much
better and as David already said: "It *would* be sensible to
provide the functionality from within Emacs once and for all" - at least
IMHO....

Hmm... all the users I know sooner or later asked me about some unexpected
behavior from `undo' and after I explained to them how it works, they all
learned to like it.

Even tho I did mention redo.el as an alternative, none of them ever switched
to using redo.el, instead they started to complain about other programs not
having a real undo like Emacs's.
