REVISION SUMMARY
  There is no explication of what is the intend of that check and what is the
  alternative.
  
  I suspect this comes from the transition to the "unified test" format circa
  
  2010. With the non zero return explicitly listed in the output explicit $?
  
  checking became Redundant. However there is valid use case for checking $? so I
  am dropping this check.
