REVISION SUMMARY
  For reasons I don't understand, Python 3.8 is outputting a different
  lint in the traceback than prior Pythons.
  
  The lines in question are:
  
    flagutil.addflagprocessor(
        REVIDX_NOOP, (noopdonothingread, noopdonothing, validatehash,)
    )
  
  Python <3.8 prints the 2nd line but 3.8 the first line. Perhaps Python
  changed its traceback logic to always print the first line of a
  multiple line expression?
  
  Whatever the case, with this change, the test now passes on
  Python 3.8.
