    I will look at using this in cua mode.  Maybe other modes which
    remaps undo should/could use this too?

It is very possible.  But we need to think about how to make
undo-in-region work right for these things.

It could be the undoable setq operations in ses.el are associated with
a change to some part of the buffer, in which case they ought to be
recorded that way.
