Sorry, but that just isn't true and never was. Having a line wide limit 
of 80 characters while forcing tabs to be 8 characters long limits most 
code to just 72 characters. And even less (max 64) inside constructs 
like if, for or while.

The only outcome of that totally silly rule is that variable names will 
become shorted to silly acronyms almost nobody does understand make code 
unreadable.

I always feel like beeing in the IT stone age when programmers thought 
they have to use variable names like a, b and c to save storage, memory 
or to type less when reading linux kernel code.
