I was using the distro-provided version of black, 22.8.0, during the blackify series. There's a newer version out however, 23.3.0. Bump this, applying the various changes it introduces in the process. Change-Id: I3442a7ddaf0cb35f37b84bdbe06625a28e982dba Signed-off-by: Stephen Finucane <stephenfin@redhat.com>
