[Vladimir Kazanov]

Hi Mattias,

Thanks for noticing this!

Got it, thanks. I forgot about relint! Regex performance is easy to
get wrong. I'd really like peg.el to be merged and used for this kind
of parsing.

Anyway, can you please take a look at the patch? It fixes the problem
noticed by relint as well as a couple of other minor things, and adds
tests to make sure regexes work the way I want them to.

Thank you
Vlad
