Details:

This is apparently a common problem that lots of people complain about:  A
user reconnects to an old screen session, but they can't run X11 apps, because
the DISPLAY variable in the session is stale.  

I notice that gnu screen correctly picks up the terminal size, type, and
attributes from the environment.  So I don't see why the same can't be done
with the X11 DISPLAY variable.  (Although there perhaps should be a command
line option for screen to do this, in case the user really wants DISPLAY to be
something different.)
