If that's the intent of the X code... I've actually seen cases where the 
hostname "unix" gets looked up, so maybe the rule is "unix means the local host 
if you don't have a machine named unix".  I'm not sure if that was X11 software 
or something else trying to interpret $DISPLAY, though; I was looking at DNS 
packet traces.

In this case, ":0.0" vs ":0" is even more straightforward.  According to the X 
man page I just looked up, at least, the default screen number is zero if 
omitted (not some changeable per-display default screen number), so counting 
those two as the same should be easy.
