Subject: [PATCH] A few small changes to make the PuTTY source base more usable
 as a basis for other terminal-involving applications: a stub implementation
 of the printing interface, an additional function in notiming.c, and also
 I've renamed the front-end function beep() to do_beep() so as not to clash
 with beep() in lib[n]curses.
