The variable has_double is true when the kernel reports multiple fingers via the
BTN_*TAP keys. This is the case for the macbook pads, and I would imagine it to
be true also for the clickpad soon. The clicking-on-lower-portion-of-pad is
interesting for both devices. In other words, perhaps the logic should be
reiterated?

Cheers,
Henrik
