I have no problem with making clang-format format things "correctly" and I am 
happy to add code. But I think we are doing the average clang-format user a 
disservice if we provide options for every such corner case. Let's settle on 
one good-enough behavior and go with that for everything/everyone.

I don't think that's true for the alternative I am suggesting.

As we can implement this without additional flags (it doesn't contradict any 
style guide I know of), I think this would be strictly preferable.
