I think programs should not have a wrapping limit, each line should be a logical thing and if it long for a good reason, it get to be long...
"But I like to diff it side by side"
Yeah but that's a tool issue!
"But github something something"
Git is not my boss why's it yours?
That said I would like a programming editor that could wrap comments, and comments ONLY. This is the only part of a computer program that feels like it should actually text-wrap, to me.
