The problem is that the code for focusing is buggy, especially when
focusing over screen-boundaries. Without focusing, much of the actions
needed for focusing need to be done anyway (updating indicators, bars,
...). (Though for example I'm not sure why switch_frame_hook is run
unconditionally even if no focusing is done).
Just doing the focusing unconditionally makes the code much easier
(20 lines less in exchange_with_frame) and get rid of all those hard
decisions.
The only difference in behaviour visible to the user is that swap with
two arguments (which I do not know if anyone ever did except for testing)
will change focus. In the irc discussion about this issue, people
considered that more natural than not doing it.
