Dmitry, please use this instead of my previous patch. Thanks to
Vincent for the code review , fixes, and testing.
ati_remote causes repeats after only .23 seconds with my remote and
makes it hard to use comfortably. Make a precise way of setting the
repeat delay time in milliseconds and default it to 500ms. The old
behavior can be had by setting repeat_delay = 0.
