Fix curses quitting when trying to move

Browse Source 
parse_escape_sequence changed getch timeout, but when receiving
a certain escape sequence, it returned without changing the
timeout back. This caused all subsequent getch calls be
non-blocking, and getch returns ERR when there's no input
waiting in that mode.

NetHack interprets ERR as the terminal going away, so performs
an automatic save.
