Braces should be used everywhere. Not requiring braces around statements leads to problems with nested one-line for and if statements, for example.

Where is the issue for this @ianjfrosst?

Closed in favor of #93.

Indentation is arguably much more important than braces for these issues, and indentation is already enforced. However, since there is disagreement on whether to braces should be required on single-line blocks, we'll err on the side of caution and require them everywhere.
