curses message suppression

The curses interface was using 'moves' as if it meant "moves" rather
than "turns".  Typing ESC at >> (curses' terser version of --More--)
prompt would suppress messages for the rest of the current turn rather
than just the rest of the current move.  So if the hero got an extra
move due to being Fast, there would be no feedback during that move.
