I am afraid I do not have access to that book (yet).  If you wish to
make a specific point based on your reading, you will have to be
explicit.  Thanks for the reference, anyway!

I find the new undo/redo mechanism, as proposed by me (and keep in
mind that I just observed the mechanism already used by joe and vim),
and implemented by Kyle, better than the old one, both intuitively
(this might be biased) and logically (less memory usage -- repeated
undo/redo sequences do not get recorded uselessly).

Just like Kyle, I would like to base my opinions on formal research of
the UI-s.  But I cannot, at least not yet.
