there should be no change to existing behaviour) and are set and shown with set-option -p and show-options -p. Change remain-on-exit and window-style/window-active-style to be pane options (some others will be changed later). This makes select-pane -P and -g unnecessary so no longer document them (they still work) and no longer document set-window-option and show-window-options in favour of set-option -w and show-options -w.
