There's no hard rule on comment line length. I routinely advise people to wrap anyway, for legibility. Humans tend to have trouble following long lines with their eyes (I sure do). Typographic manuals suggest to limit columns to roughly 60 characters for exactly that reason[*]. I'm not the maintainer here, so this is really advice, not a demand.
