    ci/check-commit-log: Ensure valid cogl and clutter prefixes
    
    Clutter is a "scope", so everything under should be its own
    "sub-prefix", e.g. changes to ClutterActor should be prefixed
    'clutter/actor', ClutterFrameClock with 'clutter/frame-clock',
    CoglFramebuffer with 'cogl/framebuffer' etc.
