NOTE: I was careful to make each change in a manner that preserves the existing diagnostic output (usually by ensuring that no lines were added or removed). This means that the resulting source files are not as nice to read as they were at the start. But we will have to review these cases by hand anyway as follow-up work, so cleanup could reasonably happen then (or not at all).
