    Avoid noise from python bytecompile on non-python pkgs (RhBug:539635)
    - If a pattern doesn't match, we'd prefer an empty list instead of
      unexpanded garbage thank you... nullglob shell option is just what the
      doctor ordered but unfortunately its a bash-specific thing. Otoh there
      are number of other bash-specific scripts in rpm so probably not
      much of an issue...
