Title: Max line length = 115

# What
I would like to propose the maximum line length to be 115 characters. I find that this is an optimal number for viewing Github diffs without having to scroll sideways. I've had highlighting in my Vim setup for at least 6 months now and find 115 characters to fit really well in half of a 1920px wide screen.

I also will say that although 80 characters is pretty tried 'n tested, this is almost 2015 and screens are big now. It's time for a new optimal number and I feel we should consider 115.
