Well, it's a definite improvement (thanks) in that a mouse click and
release near the margin no longer does an unwanted region selection.
However, now the down mouse event has no effect, and scrolling only
occurs on release of the mouse. I think it would be nicer if it were
the other way around. But maybe I'm just being greedy. :)

It is still hard to use the mouse to select a region that starts near
a window edge and requires horizontal scrolling (because the size of
the selection increases in jerks), but this is probably an inevitable
consequence of hscroll-step being 0. I should probably set my
hscroll-step to 1.

Or maybe I should turn off automatic-hscrolling altogether, to get a
behaviour similar to vertical mouse scrolling. But then even trying to
drag a selection past the edge of the window does not cause it to
scroll.

This is probably entering the "need horizontal scroll bars" territory,
which is obviously not a subject for this time.
