I'm fine with 110-140 ... I'm even fine with it being longer if it feels more natural. 

Most lines will be shorter than the 112 limit of Github, but most code is in an IDE where about 130-140 is normal on screens now.

In other words, if every single line was 140, it would be overwhelming, but when most are going to be far shorter, occasional lines > 110 are fine and it's better to avoid awkward wrapping. I turned off the auto-format on my IDE as sometimes it was annoying to have a line wrapped just because it's 1 character over.
