Well said, I agree.

Also, as touched on by the others, the current line width allows me to
read two code windows side-by-side comfortably on my trusty X200, where
~160 characters fit on the screen horizontally.  Bumping the limit up to
100 characters would certainly take that away or make it much harder.

I'm in favour of keeping the line limits as they are for the time being.
