I doubt Richard deliberately used window configurations in
`adjust-window-trailing-edge'.  Unless we can get `enlarge-window' DTRT
in all cases (which seems a rather challenging task IMHO) saving window
configurations is an effective albeit somewhat expensive way to handle
this and similar behaviors.
