After thinking about it, it is probably the best thing to do.
While it is not realistic to do so, it is also not realistic to use
reflection_min/max other then 0/1 for fresnel reflectivity, so the user 
specifically asked for it...

Btw, IMHO the docs should mention that for realistic reflection, the 
fresnel keyword should be used together with reflection_min/max of 0/1.
For someone who doesn't the fresnel function and/or it's implementation
in POV this isn't obvious.
