 	the worm instead of leaving it off the map; place_worm_tail_randomly()
 	reverses the segments and can throw some away if there isn't room,
 	but throwing away the extra segment removed the worm from the map
+using 'O' to try to change 'symset' was a no-op; 'roguesymset' worked
 
 curses: 'msg_window' option wasn't functional for curses unless the binary
