Package: Emacs
Version: 30.0.50


Currently, wheel-up/down events are generated in most setups instead
of the old mouse-4/5.  There are still two exceptions:
- X11 builds not using XInput2.
- text terminals.
The attached patch intends to fix the second bullet.
Text terminals themselves only give us info equivalent to `mouse-4/5`
and don't actually tell us that it's a wheel movement, but we can still
turn those things into `wheel-up/down`.

This is related to bug#49803.

The second step would be to do something similar for the non-XInput2 X11
build: make it generate `wheel-up/down` events according to
`mouse-wheel-down/up-event` settings.  Then packages like
`completion-preview` and `mwheel` won't need to pay attention to the
(confusingly named) `mouse-wheel-down/up-event` vars any more.
