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.
I never said it was better than anything else. I said that I trusted the developers to get code formatting done right. I also didn't say that other tools couldn't do something, I was attempting to explain the philosophy behind this tool by comparing it to a theoretical tool that has a different philosophy. (More concretely, indent, which is used for indentation, doesn't support line breaking, to my knowledge. So, it is one such tool with an alternative philosophy.)

I don't particularly care about other tools (and I'm not making comparisons to any of them), I care about making the code base more consistent and maintainable. That's my goal. Clang format is a tool that I'm using to achieve that goal because no one else proposed anything else first and I'm familiar with the tool and it's quality.
