How to avoid page-breaks inside paragraphs?
The style spec for a document requires that pagebreaks come between paragraphs or list items, so paragraphs are never split across pages. (The content is specced so that paragraphs are always short enough for this to be sane.)
How do I accomplish this? I looked into \penalty, which is mentioned in this answer, but it appears to be undocumented both on the ConTeXt Garden wiki and on the mailing list. There are a number of un(der)documented "penalty" commands such as \widowpenalty that control various aspects of paragraph breaking, but nothing that I can find that directly controls "to break or not to break" in absolute terms.
