Even worse--the appearance of DISPLAY in the environment is arbitrary.  I
hardwire mine on some systems to point to a specific location, whether I'm
planning on using it or not.  It could be set and entirely unusable.

Or $SSH_TTY.

I'd trust checking for ssh variables far more than I'd trust looking for
DISPLAY, simply because people might set DISPLAY from a telnet or ssh
session, but you wouldn't set ssh variables from X.
