If the Wiimote is already paired, it won't appear in the "discoverable
and not already setup" devices list in the wizard.

But your point is correct.

Either way, I think I'd do the work so that the "proper" pairing can be
done, and add a warning at the end of a failed pairing process for a
Wiimote if pairing failed, mentioning which way you should press the
buttons to have it always paired.

I'll get on that as soon as your patches make it into bluez master
proper.
