nit: No need for braces (single line if clause).

[David Tseng, 2014/08/21 16:17:56]

Mixed on this one. The conditional is multiple lines, so generally braces are
also required? I'm ok either way. Changed to stay consistent with this file.

[Finnur, 2014/08/21 16:23:32]

Yup. It is a common misunderstanding of the style guide that because the
*conditional* is multi-line then single-line if and else clauses that follow
need braces. They don't.
