Thatís not a clear win. Because much CPAN-related infrastructure insists on a single dash, almost all modules have a single hyphen, which means the more fastidious form picks up nearly all descriptions correctly. If you allow multiple hyphens, you recover some false negatives, at the cost of some false positives, where the description of the module is malformed but thereís a line with multiple hyphens somewhere nearby. Matching ' --? ' at that point has a couple fewer false positives and still almost no false negatives.
But because of the effect of CPANís rules, itís hardly worth bothering either way, and I prefer to get output thatís consistent with other tools.
