  By the way, I have the feeling, that this is may be a "bug" not worth
fixing.
  Why? It is extremely rare that one finds this behaviour (I have never seen
it in *any* of my scenes; I have never had a scene such that this would be
seen). Of course that's no reason to not to fix it, but I have the feeling
that adding a check for this could slow down all specular/phong calculations.
  I don't think it's worth slowing down the rendering of *all* scenes which
use specular/phong just because in one case in a million you might find this
little annoyance.
  Of course if a fast solution is found, then it's worth fixing, but somehow
I have the feeling that there might not me a fast solution (fast meaning
for example just few multiplications and additions).
