One sentence, one line Patterns chapter

This was mostly mechanical. There are only two things of note:

1. A couple sentences ended with commas instead of periods. I changed
   them to periods. They were both in the Binding Modes section, so I
   assume they were added together.

2. In the static/dynamic behavior for or patterns, for two sections, I
   separated lines based on commas instead of the one really large
   sentence they are.
