Why doesn't TMemo have OnMouseWheel, OnMouseWheelUp and
OnMouseWheelDown events? Yet TListBox does. Is this by design, or an
oversight?

Probably an oversight since wheel events were added a little later and even without my previous patch (see the topic about wheel events in non-TWinControl controls), TMemo was a descedant of TWinControl. I attach a patch against revision 15313 which adds these properties. I tested them and they work fine.
