    Revert "Make FlexeLint a little bit happier"
    
    The fact that a boolean argument is present does not imply
    that it's true.
    
    This reverts commit 57cd74cf51b63a54df68600a573eb0e20e2a6c7a.
    
    I promise to look after this once I got my Flexelint config back,
    which, unfortunately, I lost during a reinstall. Yes, I do have
    a backup, but cannot access it easily at the moment.
