 412
 413      Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
 414                The important thing to know is that odd numbers are considered
 415                good, while even ones are considered errors.
 416      Bits 3-15: actual status number
 417      Bits 16-27: facility number.  0 is considered "unknown"
 418      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 419                  output the message (which, for random codes, just looks ugly)
 420
 421      So, what we do here is to change 0 to 1 to get the default success status,
 422      and everything else is shifted up to fit into the status number field, and
 423      the status is tagged as an error, which I believe is what is wanted here.
