in frame.c looks plain wrong and should probably just be deleted:
frame-selection is never intended to raise (or lower) any frame.
If this `raise' is really necessary, then it needs a much more
extensive
comment justifying its presence.
Adrian, could you remove this code, or justify clearly why it's
here?
I think it is there because we need to raise another (visible)
frame when
a frame is deleted. This is standard behavior (and sensible).
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).
