    407 
    408      Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
    409                The important thing to know is that odd numbers are considered
    410 	       good, while even ones are considered errors.
    411      Bits 3-15: actual status number
    412      Bits 16-27: facility number.  0 is considered "unknown"
    413      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
    414                  output the message (which, for random codes, just looks ugly)
    415 
    416      So, what we do here is to change 0 to 1 to get the default success status,
    417      and everything else is shifted up to fit into the status number field, and
    418      the status is tagged as an error, which I believe is what is wanted here.
