Update style.9 to reflect consensus on developer's mailing list
allowing redundant braces.

Bump date.

r284608 (by imp):

Back out contested change until dispute is resolved. This proved to be
more contentious than I expected.

r285219 (by imp):

The results of the vote are in. This reflects that vote. Single
line statements inside of braces is recognized as an acceptable
style.
