I don't understand the following passage:

"When matching GROUP BY names, prefer local FROM columns first, then
SELECT aliases, and then outer FROM columns (Tom) 

This change was made because it is considered more consistent than the

more thorough documentation on that subject.

Also, I've included a couple typo fixes below.
