Yeah, in an ideal world, that would be better -- and I've tried writing like that ... but sooner or later I end up wanting to open the file in a location where the wrapping isn't configured properly, and all of the super long lines look terrible.

So I just tend to hard-wrap manually, out of habit, even when writing in a .txt file or an email. In fact, it's hard to stop myself from doing it in this textarea ;)

What editor do you use? With vim I think I've always been able to select comments and "gq" them to autoformat them to whatever the linewidth is set to.
