Done.

My saying "traditional C Mode fontification" was just a pompous way of
saying "parameters fontified as well as variables", but avoiding
repetition.  Sorry for the misunderstanding.

There is no such description, and I can't see that it would be very
helpful to anybody, particularly considering the time taken to write it.

It would be thoroughly unreasonable to expect c-ts-mode to fontify
identically to C Mode in every respect.  But I think having declarations
of both parameters and variables fontified, but not their uses, is a
worthwhile strategy.
