                The important thing to know is that odd numbers are considered
 	       good, while even ones are considered errors.
      Bits 3-15: actual status number
      Bits 16-27: facility number.  0 is considered "unknown"
      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
                  output the message (which, for random codes, just looks ugly)

      So, what we do here is to change 0 to 1 to get the default success status,
      and everything else is shifted up to fit into the status number field, and
      the status is tagged as an error, which I believe is what is wanted here.
