Thanks.  For the record, here's a much easier way of reproducing the
bug:

  emacs -Q
  Resize the frame by dragging one of its edges with the mouse
  M-: (modify-frame-parameters nil '((fullscreen))) RET

IOW, the problem was that when 'fullscreen' was present in the frame
parameters with a nil value, the frame dimensions were reset to the
"original" size, which was recorded only during startup, and thus
disregarded later changes of the frame dimensions.

I think I fixed this in revision 112114 on the trunk.
