Those who lived through the (text-mode) WordPerfect era may remember 'widow and orphan protection' as being one of the features which was advertised for this program, i.e it could be set to either move that orphaned first line of a new paragraph to the next page or move a few extra lines or a whole paragraph to the next page to keep the widow company.

Text mode WP is the reason I hate almost all word processors, everything else is tepid goat piss by comparison.

I remember using WordPerfect in that era and never understanding what that feature was. It seemed implausible to me that it was actually protecting human widows and orphans, but I couldn't imagine what it had to do with text layout!
