This is a behavior which depends on the window-management policy, so
it's the responsibility of the window-manager (which may even decide
that the focus should return to some other application, which would make
a lot of sense if the frame was created via $EDITOR=emacsclient).

So, I'd still want to know what undesirable behavior would happen under
NS if we don't call Fraise_frame here (and also, why it needs to be
called here rather than elsewhere).
