Short lines (about 72 chars) are easier to read prose. But most code is tabulated, and is much less dense than prose. I tried a few different thresholds over the years and I finally chose 100 chars. It is a good compromise, wide enough to not be obnoxious and enabling long names. And still narrow enough to display two columns on a single wide screen when needed.
