Indentation differs from style guide

According to the style guide, code should be indented with 2 spaces, currently 4 spaces are used.

Each level of indentation should be 2 spaces.

The default is actually 2 spaces, but this is overridden by VS Code's formatting options. Thank you for pointing this out, since it's worth thinking more about how much we want to enforce the style guidelines over environment defaults.
