    fileUtils: Delete deleteGFile hack
    
    It is true that delete is a javascript keyword, but that doesn't
    prevent it from being used as method name - there are event built-in
    types like Map or Set with delete() methods!
    
    So if that hack was ever needed, this hasn't been the case for years
    now; just removed the hack now.
