I was unclear: I hadn't figured out how to get the relevant terminal
programs to generate either wheel-up/down or mouse-4/5. It looks like
iterm2 sends mouse events using the xterm protocol, which xt-mouse
then posts as mouse-4/5 events. I guess we could modify xt-mouse to
optionally send them as wheel-up/down instead, but that feels like a hack.
Do we have a generic mapping mechanism for mouse events? I guess
theyʼre not keys, so keyboard-translate won't work.

This is using emacs -nw, so the gui api is not involved.
