Mms proposed updates

These are my proposed updates, mostly reflecting the things that I've been doing without documenting them. Feel free to tear them apart. I'll annotate changes that I think need explanation.
I am opposed, but not super strongly. I think the 80-character limit generally helps in writing better code, because it forces you to be more critical about long strings of logic and chains of functions on a single line.

Also, comments are much more readable at 80 characters in my opinion.

```
Anything from 45 to 75 characters is widely regarded as a satisfactory length of line for a single-column page set in a serifed text face in a text size. The 66-character line (counting both letters and spaces) is widely regarded as ideal. For multiple column work, a better average is 40 to 50 characters.
