Something like that (I didn't yet have time to test the patch).

My reasoning is simple: switching windows by a keyboard command or by
clicking the mouse is an intentional user action, for which he/she is
fully responsible.  By contrast, moving the mouse pointer can be
accidental, so disabling only it in these situations makes much more
sense than disabling window-switch entirely.

Yet another alternative would be to treat the select-window event in
the middle of a key sequence specially, but I'm afraid that would be a
much more complex and dangerous change (as everything inside
read_char).
