Ciao,
This patch adds support for comment fontification using the doxygen parser:
https://github.com/tree-sitter-grammars/tree-sitter-doxygen
This is the same parser used by nvim treesitter and seems to be quite stable.
The attached screenshot shows the result.
This patch also works with emacs 31.
Thanks.
Vincenzo
