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.
