DISPLAY environment variable from login(1)

[Bill Janssen]

Actually, using the tty information for this is an extremely fragile
option.  The server could have been started with a different display
number, or the screens could have been switched.  Some type of
meta-environment variable is really needed for this kind of situation
(multiple logins under the control of one "session").
