Comment 3 for bug 252512

FWIW I don't find over-long comments to be a problem (any more, anyway; they used to be a problem when people failed to find the attachment feature, but that's been fixed). If comments are long and ranty, then the rantiness is the problem, but more often than not I find that long comments come from the more thoughtful contributors who have taken the time to think about what they're writing. We should encourage rather than discourage such behaviour.
