For key repeats X creates two corresponding KeyRelease/KeyPress events.
So, first we check for the KeyRelease event, take a look at the next
event in the queue and look if they are a matching KeyRelease/KeyPress
pair. If so, we mark the current KeyRelease event as a KeyRepeat, and
set "next_event_is_a_keyrepeat" to "YES" so that we know that the next
