This is so, but why would XEmacs need to interpret the value of the DISPLAY
environment variable? That string is meant to be passed to the X libraries
for communication with the server, not interpreted by application programs
(regardless of the fact that historically programs have done that, it is a
What possible need could XEmacs have to do that?
Now I look into it, XEmacs does leave the parsing of the DISPLAY variable to
the X11 libraries. Still, a lot of the point of X11 is that programs written
with one version of the libraries can display on servers written with
another version of the libraries, even on another architecture; randomly
changing the format of the string makes that harder.
(In practice, people should be tunnelling the X11 connection over SSH, where
this won’t matter, as far as I can see; SSH passes the DISPLAY string to
xauth(1), it doesn’t do the parsing itself.)
