Don't get carried away with options, we have too many already and I'm very
unlikely to add even one more for this. We just need acceptable defaults for
most of the people who will use this. If in doubt copy what emacs or xterm does.

In less, but also in copy-mode. No modifier keys seem to have any effect. It
could be my terminal environment, I guess? KDE/Konsole.

Well, 3 seems natural for me. With mouse-enabled vim, the mouse wheel also
scrolls 3 lines. I don't think it's Konsole doing that, I assume it must be a
default in vim.

It would be nice to have this be configurable, and it also makes sense to me
that both scroll rates be the same.

Makes sense.

Good question! I guess the catch-all answer is to provide configuration
allowing the user to set fast and slow scroll speeds in addition to the
standard one. Maybe a single configuration option could take one, two, or three
parameters:
mouse-scroll-speed <normal> [<fast> [<slow>]]
I would guess a sensible default would be that fast is double the value of
normal, and slow is 1?
