Scrolling down as long as possible by using the mouse wheel stops only when the last line of the buffer becomes the first visible line of its frame, so that the rest of the frame becomes empty. This is rather unaesthetic. Also, it is inconsistent with scrolling down by using the down-arrow key, which, as in other applications, stops already when the buffer still occupies almost all of its frame.

Doing this has no effect. Maybe because I use the NS-port: The documentation of this variable speaks of GTK and Motif ports.
