Yeah, I'm pretty sure it does, although I've never poked deeply enough / understood elisp well enough to know exactly how it does it.

Swapping out those regexen you have wouldn't be too much of a challenge, I don't think, at least for a first shot at it.

I'm more interested in the general structure of managing the counter, applying the various faces to lines, etc.

My email is in profile if you want someone to attempt to clean it up a bit (insofar as I'm capable of doing so) :)
