chromium style says: "For function declarations and definitions, put each
argument on a separate line unless the whole declaration fits on one line."

http://www.chromium.org/developers/coding-style#Code_Formatting

doing that would make the wrapping less crazy here too

clang-format bug :(

Fixed manually for now.

clang-format appears to have been updated and now wraps this more sensibly on
its own.
