Subject: [PATCH] tty: ^C while prompted re-displays last message - attempt to
 determine if tty_wait_synch() is called during the ending  dialogs due to an
 interrupt, and not re-display the previous message  at the wrong time - also,
 "msg_window display anomaly" fix was missing code to still treat ^P  properly
 while in a prompt
