Alas, it happens regularly in real life. The groff line-filling algorithm would have a hard time predicting a page break, for the break is usually the result of a yet-unseen .br, typically hidden in the text of a macro invoked by a line trap. Back to Branden's original question. I woulld expect the hyphenation count to be zero at the top of a column or page. Doug
