Enabling mouse-wheel-mode binds two different mouse events, depending on the operating system. The correct way to check for those events is by checking mouse-wheel-up-event, as explained in the ELisp manual. * test/lisp/mwheel-tests.el (mwheel-test-enable/disable): Check mouse-wheel-up-event instead of mouse-4 to make the test work irrespective of the platform it's running.
