The way I see it, the `other-window' argument to pop-to-buffer should be
able to provide such settings as well.  I.e. they could be provided both
by the user in s-d-b-n and by the code in other-window.  And of course,
application-provided settings would only take precedence over global
settings and not over user cutomizations.
