The proposed feature is that any _scrolling_command_ (e.g. C-v, M-v,
mouse-wheel, ...) should perform its scrolling without altering the
location of point (wrt its buffer).  But any command which changes
either the location of point (wrt its buffer) (e.g. "C-u 200 C-n" or
the buffer text should check whether the point is currently visible,
and if it isn't visible, it should trigger an auto-scroll to make
point visible (exactly as happens now).

In short: point movement should trigger auto-scrolling (as now), but
scrolling should not move point.
