I would agree with this.  When I wrote the original mouse wheel
support (now long since changed to better implementations), I created
the mouse-wheel event because (to the best of my knowlede, at the
time at least) these events hadn't been standardized into a
mouse-4/mouse-5 event at that time in X.
