Can you link to the scanned PDF and your GitHub repo? I've noticed a few places with mismatched brackets, such as "(....]", and wanted to check to see if they were mismatched in the original or if that's just a transcription error.
edit: Found the original at http://hall.org.ua/halls/wizzard/pdf/vaughan.pratt.tdop.pdf and your repo at https://github.com/tdop/tdop.github.io. Am reading the paper now, it's not one that I'd read before so thanks for posting it, and will send a pull request with suggested fixes when I'm done.
There seem to be a number of places where you've changed hyphens to em-dashes. (E.g.: "This argument is independent of whether we specify program control explicitly, as in Algol—like languages, or implicitly, as in Planner—Conniver-like languages.") It's a bit confusing to read. Would you possibly mind fixing this? Thank you!
I collected up a number of nits like this, plus some more meaningful transcription errors, into a branch, and have sent a pull request: https://github.com/tdop/tdop.github.io/pull/2
I've tried not to change anything beyond the typography, but it's tricky to get perfect. It's on GitHub, so feel free to chip in.
