BUILD: Re-enable -Wimplicit-fallthrough

Getting rid of this warning is cleaner solved using a 'fall through' comment,
because it clarifies intent to a human reader.

This patch adjust a few places that cause -Wimplicit-fallthrough to trigger:

- Fix typos in the comment.
- Remove redundant 'no break' that trips up gcc from comment.
- Move the comment out of the block when the 'case' is completely surrounded
  by braces.
- Add comments where I could determine that the fall through was intentional.
