> A local run of HEAD (as of Jan 17, I'm at daec3e) with
> "./configure --with-pgtk" has mouse-wheel-up-event set to wheel-down

This has been changed on `master` around Jan 19.  Now `mwheel.el` uses
`wheel-up/down` unconditionally and `mouse-wheel-up/down-event` is only
used for *other* events (defaults to `mouse-4/5`).

I didn't both to check the code to see if that can happen (especially
since there are various possible encodings coming from the terminal).
The way wrote the code, it'll do the right thing if/when the rest of
`xt-mouse` manages to generate those events, but indeed it might be the
case that currently this will never happen.
