If there so some tool everyone uses that constraints the width use that. Otherwise treat programmers like grown-ups and let them break their lines where they want. The width of a github code window is about 120 characters. That's suggested max line width because horizontally scrolling diffs during a code review is terrible. It is rare that we have any lines close to that long though.
