Don't recommend 80 char line limitation

[elizabethshirley]

I think the 80 character line limit clashes with the previously mentioned push toward using the newest tooling that you can. (C89 v C99 v C11) Additionally, most systems are using widescreen monitors, even the raspberry pi is in wide screen aspect. Even using an outdated IDE like KEIL, which when crowded with frame and panels, still leaves ample room to edit code.

I think, if you're going to hold onto the 80 character line limit, then you should use Linux's 8-space tabbing, as Torvalds recommends, since that enforces code simplicity.
