Slow parsing with inline HTML on 0.4.14

[youngbrioche]

Converting a document with a certain amount of inline HTML is very slow. The original document contained way more content than just the <pre> tags, thus resulting in even higher conversion time. I stripped it down to just the inline HTML in order to ease reproduction.

I created a gist for the mentioned document.

$ peg-markdown -v

$ time peg-markdown document.md
[OUTPUT STRIPPED]
real    0m4.217s
user    0m4.202s
sys 0m0.009s

Suprisingly, plain old Markdown is pretty fast at converting the document:

$ time markdown document.md
[OUTPUT STRIPPED]
real    0m0.049s
user    0m0.042s
sys 0m0.006s

Interesting. Oddly, I don't see the slowdown when I replace the pre
tags with div tags, but I can't see ANY reason for the difference, since
pre and div are handled in exactly the same way...

I'm not maintaining this project actively, but thanks for the bug
report. I'll take a further look if I have a chance.
