[-- Attachment #1.1: Type: text/plain, Size: 490 bytes --]

The attached patch adds the following faces:

- font-lock-escape-face
- font-lock-number-face
- font-lock-operator-face
- font-lock-property-face
- font-lock-punctuation-face

font-lock-property-face inherits font-lock-variable-name-face which matches the behaviour of cc-mode and python-mode.

font-lock-escape-face inherits nothing. In python-mode, it inherits font-lock-constant-face, but not in cc-mode. Do we want it to inherit anything?

Hopefully I put everything in the right place.
