Subject: CC Mode 5.33 (Emacs-Lisp); Faces applied in wrong order on "#ifndef"
Date: Fri, 24 Mar 2017 16:49:12 +0000

When fontifying '#ifndef', cc-mode applies font-lock-preprocessor-face
to the entire string and also font-lock-negation-char-face to the 'n'.
Preprocessor-face is applied on top of negation-char-face; I think it
should be the other way around.

Describe-char says that both faces are applied.  The theme I use
(base16-default-light) only sets :foreground for both faces; if I set
(for example) :weight bold on negation-char-face, the bold shows
through on the 'n', though :foreground continues to be set from
preprocessor-face, confirming that both faces are applied and that
preprocessor-face is overriding negation-char-face.
