I can't say for sure at the moment. All I can say is that I didn't find
anything in the code that would explain that wording, but I might have
overlooked something. I guess experiments may be needed.
Maybe the sentence was placed there not so much due to unexpected
effects on the looks_like object, but unexpected effects on the light
source itself. (For instance, whether or wheter not POV-Ray translates
the `point_at` location along with the parallel light source, either way
the effect may be surprising to some users.)
