Squeeze inline /help table width to 110 characters

[rolandwalker]

Description

Rewrite nearly every line of /help to make it short as possible, using every trick to get the width of the table down from 133 characters to 110 characters.

Along the way the entries become a little more consistent.

I'm a fan of wide text on modern monitors, and definitely think that 80 characters is too narrow outside of specific cases such as side-by-side comparisons.

But at 133 characters, perhaps the /help output was not friendly to everyone, as it should be.
