Confusing description for dictionary indentation

Hello there,

I'm seeing 2 issues in Python style guide:

1. Chapter 3.9 is missing.
2. In chapter 3.4 Indentation, the 2nd example is incorrect. The comment is "# Aligned with opening delimiter in a dictionary", but this example is not aligned with the delimiter, using "4-space hanging indent" instead.
