Totally agree with Barry, but also wanted to mention that occasionally a 160 character line is a useful way to hide unimportant information. For example, a long error message intended for users, where the developer reading the code is fine to just skip over it, can be the difference between seeing all the code on a single screen and having to regularly scroll to get the actual meaning of the function.
