The function returns the frames that it considered and what action it
took with it.  It will not necessarily return an entry for each
existing frame.

I don't see why that would be problem.  The returned list simply
wouldn't mention any of the existing frames, so if you want to delete
those you'll have to call `frame-list'.

Look at it not as "move stuff from frameset-restore to its caller" but
as "split frameset-restore into two functions".
