Re: Feature request/RFC: proper highlighting of code embedded in comments

[Stefan Monnier]

FWIW, in sm-c-mode.el (in elpa.git), CPP directives are treated as
comments, and since they do contain code, I have to solve the same kind
of problem.

I (ab)use for that purpose a syntactic face function.  The starting
point is:

  (setq-local font-lock-syntactic-face-function #'sm-c-syntactic-face-function)

Take a look at sm-c-syntactic-face-function and especially
sm-c--cpp-fontify-syntactically to see how I try to re-use the existing
font-lock functionality.

It's a bit gross, tho.
