That's one way to look at it.  If you look at it w.r.t XEmacs, where
they have `button1' and `button1up' (IIRC), I prefer to consider that our
`mouse-1' is an up event (and we simply define the click as happening
on the up event).

The point here is just that the way the comment is written makes it
sound like we'd throw away all events (both up and down), whereas we
only throw away the "companion event" (either the up or the down one,
depending on the specific kind of event).
