Polish formatting

The sources affected by this commit have drifted in style since earlier
polishing commits such as f34d1f4 and a155518. The shared IDEA style
configuration file can help avoid this drift in the future. Simply run
Code->Reformat Code at the project level prior to committing. Note that
this code style configuration is not perfect, and not every change it
makes should be checked in. The ideal is to simply always write code that
conforms to the style conventions, but the automated settings are there
as a helping hand when necessary.

The churn caused by drifting style and the commits that fix it damage the
utility of git over time. Reviewing changes, analyzing history, surgically
reverting commits, and many other use cases with git simply do not work as
well when styles get mixed and fixed. Let's work toward a common style.
