I wanted syntax highlighting for list item bullets (e.g. '-') in my org
mode setup.

I have a very early prototype working and wanted some feedback about
whether you would be interested in this feature upstream, or perhaps
including it in a package would be a better bet.

The code is in a github gist:
https://gist.github.com/fluffysquirrels/1aaec7cab234893bfd46cdad721dda85

The code is rough but very short and readable. I have some test cases
working, with a screenshot of how they look on my machine.

Thanks!
