lib-src/emacsclient.c (window_system): New variable.
(frame): Renamed to tty for consistency with the option name.
(longopts, print_help_and_exit): Added -w option. (Suggested by Ami
Fischman <ami at fischman dot org>.
(decode_options): Initialize display to $DISPLAY.  Handle -w option.

(server-start): Add it to delete-frame-functions.
