I'd like to make two suggestions:

1) I don't see a good reason this shouldn't just be what %p does
(that is, instead of adding %o, perhaps %p should be altered, since
this is more sensible.)

2) If %p is not changed, a knob should be made available to allow
users to invoke the %o in place of %p without having to edit the
modeline specification themselves, which is currently quite messy.
