    Ignore flake8-bugbear B023
    
    I seem to like writing code which I think legitimately use the construct
    this warns about.
    
    Drop ignoring B020, since false positives are fixed.

    Only remove empty subdirectories below a certain depth
    
    'cygport upload/stage' assumes the existence of the '<arch>/release'
    directories, so don't remove those, even if empty.
