Pro-tip: use Clang format to do the dirty job for you
(https://code.google.com/p/chromium/wiki/ClangFormat)

Thanks for the tip.

(In this case I have decided not to use the format produced by ClangFormat as it
is inconcistent with the existing format in some of the files, and in some cases
I prefer having all the arguments in one line)
