Nack.

While the origins of 80 character lines dates back to punchcards there 
is a reason it has survived the test of time.  Lines that go longer are 
hard to comprehend.  Either they are long themselves, in which case 
breaking them up into smaller chunks on multiple lines helps 
readability, or they are starting from deep indentation, in which case 
the function should be refactored or broken up so the logic is more 
digestable.
