What do you understand by "selection backward"? My intention was to
indicate that this variable controls selecting the region when you
double-click at region-end; in this it is indeed selection backward from
point, though I admit that the phrasing is not elegant.

I don't yet see your problem, because I don't know how you interpreted
"selection backward". I did struggle a bit with the name, though, and
am not thrilled with it. But if no one comes up with a better name and
you find this one unsuitable, I can certainly live with
mouse-select-region-scroll-backward.

What's not needed: the phrase "for historical reasons", a rationale for
the asymmetrical behavior, or any description of the user option? In
other words, are you saying the doc changes in the patch are acceptable?
