fix-format: 6 files left unchanged.

It reformatted 2 files (they are listed) but the final out says none have been changed.

It is a bit confusing, but the last message 6 files left unchanged is about the rest of what fix-format does behind the scenes.

We might consider capturing/parsing black's output and merge the 2 statuses.
