Added as an issue to the spec, along with the following proposed wording:

   | When a forced break occurs, it forces ensuing content into the next
   | fragmenter of the type associated with the break, breaking through
   | as many fragmentation contexts as necessary until the specified break
   | types are all satisfied. If the document is not fragmented (e.g. in
   | continous media when no fragmenting features such as multi-column
   | layout are used), then the forced break has no effect.

Think about that, and let me know if that's what we want. Alternatively
I can just define column breaks to be promoted to page breaks when there
is no ancestor multicol context.
