Sure thing.

I explained the choice of 85 in the description, and yeah, it's definitely a little arbitrary (because it already was arbitrary). I'm reluctant to add a MAX_LINE_LENGTH definition since I would think it would have been in cli.h a long time ago if there weren't some compelling reason against it.

It would be nicer if there was a way to get the width of the terminal, but I don't know for sure if that can be done reliably without relying on libraries like ncurses, which is probably unacceptable.
