Going to the trouble of shooting 480800 rays and outputing a black 
800x600 image when it already knows this is not a scene.   I can 
understand parsing the file as it might have side effects such as 
producing output for animations or something of the sort, but previous 
versions did not go through the actual process of rendering an empty scene.

Compare the output of trying to render "glass.inc" from the include 
directory:
