Or maybe even, we could benefit from a space-resolution pass in line-layout
too. Replace the white-space sequences by one unresolved SpaceElement, and
resolve those in the LineLM, at the end of collecting the inline elements for a
paragraph. 
That would probably be the most comprehensive approach, since it could then be
folded into space-start/space-end resolution (currently non-functional), and it
would make it much easier to detect sequences of consecutive preserved
white-space characters across FO boundaries...
