Format Brittany's source code with Brittany

[tfausak]

It would be nice if Brittany could be "self hosting" in that it could format its own source. Doing so would give a lot of confidence that things aren't broken, and also stand as a good example of what Brittany's output looks like.

I'm curious if using https://restyled.io/ would be an option once the initial formatting is done. This all depends on whether "self hosting" means formatting with HEAD or the most recent release.

That would probably be fine, especially with layout stability (#235). In fact it might be nice — we could recommend that other projects do that too, and we'd be eating our own dog food.

I'm not sure this is possible. Brittany doesn't handle CPP, and Brittany's own source code has plenty of that.
