How about the following idea: we create a special purpose undo list
separate from the existing one.  Every change is recorded on this list,
regardless of whether or not main undo is disabled.  After each
invocation of after-change-functions the list is emptied.

    (defmacro with-change-undone (&rest forms) ...)

An after-change-function can invoke the macro `with-change-undone' which
would undo the changes, execute the &rest forms, then redo the changes.

Surely this would satisfy both of us, no?
