This is correct WebKit style, but I'd go for chromium style since we'll have to
eventually, anyhow. The text of the initializers should all line up as you have
them, but commas go at the end of the preceding line.

Done.

I think chromium style would have the curlies on the same line separated by a
space.

The leading curly is on the last line of the initializers, the following is on
its own line.

[hartmanng, 2012/10/30 20:10:51]

Done.

[hartmanng, 2012/10/30 20:10:51]

Done.
