80 limit is something that should have been increased long time ago. Note that this limit is used since age when length of every identifier was limited to 8 characters and only one font on the screen/printer. No possibility to change font size.
God, we have different screen and printing technology now. We have very different programming languages. There's no reason to use 80 characters anymore. Increase it to 120 chars at least.
Even then it shouldn't be a hard limit. You go one character over the line? Well, nothing happens!
