Whitespace changes by clang-format.

These files are the ones with the least number of changes when running
clang-format over them and only the less controversial changes are
included, with a preference for having stay the same where things are
likely to be more controversial.
Probably not?

My point however, is that it doesn't care what the current code is formatted as, it will format it based on the settings given, in most cases. I can imagine tools which take the approach of only doing indentation or having various other restrictions put in place which effectively trust the human writing the code to do some formatting up front. This tool doesn't do that.
