  I suspect it is really an artifact of the way xray is implement - it just sets 
the 5x5 (iirc) area to be visible, and as such clears any darkness information, 
so effectively the character can see in the dark.

  This is probably reasonable behavior - if you are on a map that uses darkness, 
xray vision wouldn't let you see much if it didn't clear darkness - you can see 
through the wall, but since there probably isn't a light source, you don't see 
anything.

  crossfire doesn't have infravision, IIRC, but instead the 'you can see in the 
dark' without really explaining the mechanics behind it (which is fine IMO). 
IMO, that shouldn't let one see through walls with see in dark - it should 
basically just attune yourself to be able to see in the dark (I suppose think of 
night vision goggles - it just means you are more sensitive) - plus in crossfire 
many walls are quite thick, and any wavelength of light that would get through 
them would probably pass through everything else, which wouldn't make it all 
that useful as an image source.
