    * packages/gnugo/gnugo.el (gnugo-push-move): ...here.
    (gnugo-display-final-score): Detect resignation

     - don't special-case property value type ‘none’
     - handle subtrees on write
     - display "resign" as "resign" in move history (amazing!)
+    - avoid clobbering SGF property ‘EV’ on resignation

   - ‘gnugo-undo-one-move’ can optionally switch colors
   - ‘gnugo-move-history’ returns last two moves w/ RSEL ‘two’
