Has it though? If that were the undisputed truth, we wouldn't be
having this discussion.
If you know of a usability study that quantifies the effect of line
length on readibility of C code I'm willing to listen, and I'm sure
others are too.
Good point. As with most things related to kernel development, a
usability study or other market research from a reputable institution is
a vital first step before taking any action.
We don't have any good peer reviewed research on the subject that I am
aware of. I guess even contemplating a change at this early point would
be rash and dangerous.
I withdraw my previous comments with respect to the 80 Column Question.
Instead I would recommend elevating the WARNING to ERROR status.
