There are a lot of macros in our code that tree-sitter based C mode
gets right, so I'm not sure this is accurate.

Maybe we should grow some augmentations for tree-sitter, at least
given enough time.  Or maybe it's possible to identify the parts where
this happens by some tree-sitter indications, and tweak the faces in
those regions in some way.
