[-- Attachment #1.1: Type: text/plain, Size: 360 bytes --]

I'm just submitting C/C++ and Python for now since some of the other files are
a little more volatile currently (there are some patches in progress).

Will probably need to update this patch after Theo's stuff is pushed.

I would also like to reorganize the features to be sorted
alphabetically, but I'll wait for things to calm down a little beforedoing that.

Subject: [PATCH] Utilize new font-lock faces for C/C++ and Python tree-sitter
 use

* lisp/progmodes/c-ts-mode.el (c-ts-mode--font-lock-settings): Use new
escape, number, property, operator, bracket, and delimiter font-lock
faces.  Simplify type matching.
(c-ts-mode--base-mode): Add them to the feature list.
(c-ts-mode): Fix typo.
* lisp/progmodes/python.el (python--treesit-settings): Use new number,
property, operator, bracket, and delimiter font-lock faces.
(python-mode): Add them to the feature list.
