  sh: Forget all cached command locations on any PATH change.
  
  POSIX requires this and it is simpler than the previous code that remembered
  command locations when appending directories to PATH.
  
  In particular,
    PATH=$PATH
  is no longer a no-op but discards all cached command locations.
