Shaun, I think that a per-file list of misspelled words, as misspelled, would be simplest. (In essence, a denormalized table.) I hope to not strain credulity by stating: Typos and abnormal spellings do get fixed in the normal course of work on the sources. Not reliably at first opportunity, but when noticed. I'll see about getting a link-landing into the copyright page so that "Contributing" shows up in the site keyword index.
