Fix few punctuation marks

[petk]

• [x] I provide my work under the project license.
• [x] I grant such license of my work as is required for the purposes of future print editions to Ben Straub and Scott Chacon.

Changes

• This changes few punctuation marks (if I'm not mistaken, they should be outside of the formatted text).
