Hmmm...  size_window has a NODELETE_P argument but for some reason
adjust_window_trailing_edge doesn't set it.  On the other hand
size_window never reports failure so we would have to compare heights in
adjust_window_trailing_edge to detect whether there was a failure.

Probably using the NODELETE_P argument mentioned above.  Remains one
question: In which cases would deleting windows be an option?
