Indeed, the above are very good examples of how to contour the original problem Gabor! But the central problem is to make Good R highlighter, as I'm trying to do for the programs Tinn-R and jEdit with this functions.

Is not possible differentiate the signal minus as a simple character (word-word) from the mathematical operator minus (object-object).

I think that is more easy to remove all this functions/reserved words.
