I think this concern over an absolute limit on line length is overblown. Where I work now, we don't use a hard limit on line length. The rule is "keep it readable." That usually means lines less than 100 characters. I try to keep it below 80 myself, but I wouldn't complain about a 120 character line. I did a search through our codebase for line lengths over 80 or 100 characters and found remarkably few. Most were comment lines.
