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