Interesting idea, although 'specular off' for objects would be quite
weird.  Another problem comes with the other no_* keywords.  

no_image -> image off     would seem OK, but
no_reflection -> reflection off     would be extremely irritating since
it's not clear what reflection you actually turn off.

And now that we are talking about this stuff i would also find a
no_radiosity or radiosity on/off modifier for objects very useful.
