Please only commit blackened code. It's best to check this with a pre-commit
hook:

```
#!/bin/sh

if git rev-parse --verify HEAD >/dev/null 2>&1
then
	against=HEAD
else
	# Initial commit: diff against an empty tree object
	against=4b825dc642cb6eb9a060e54bf8d69288fbee4904
fi

# Redirect output to stderr.
exec 1>&2

black --check $(git diff --cached --name-only --diff-filter=ACM $against | grep '\.py$')
```
