The indefinite article issue is a bear and a half, to put it mildly. The sneaky thing is that Inform, internally, is effectively doing a version of Eric Eve’s Text Capture in its core code. I think I’ve figured that part out and now I’m trying to design the appropriate activity for smart handling of words like “herbal” (US pronounciation) or “unicorn”.
@Zed, worth noting: Chapter and Section headings in the documentation need to be “Chapter -” or “Chapter:” to format properly. The punctuation is mandatory. (In fact the “-” version has only been allowed since a patch I submitted last week.) This was probably easy to miss since the formatting has been broken since the release of 6M62. In the code, the dominant style is “Chapter -”.
