I find myself in possession of both time and interest. I have to
admit up-front that I don't have experience with regex code, but I do
have some experience with parsers generally, and I'd like to think
some of that skillset would transfer to this problem. I also find
regexes fascinating and extremely useful, so learning more about them
will be no hardship.

I'd happily cede to an expert, should one appear, but otherwise I'm
all for moving the regex code into a discrete library, and I'm
volunteering to take a swing at it.

Cheers,
BJ
