lily/side-position-interface.cc:278: // do not use cross_staff elements
as supports of spanners
Well, I meant to suggest "do not use cross-staff elements as supports of
objects that are not cross-staff" whether said elements are spanners or
not.

The reason is simply order of decisions in layout: before staff-spacing
we want to lay out everything possible (everything that is not
cross-staff) and then place the cross-staff objects.

It would be nice in the future to have pedal brackets, for example, move
away from cross-staff beams and slurs, but doing so would make their
position depend on staff-layout, so probably they would need to inherit
a cross-staff flag in those cases.
