 266
 267      Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
 268                The important thing to know is that odd numbers are considered
 269                good, while even ones are considered errors.
 270      Bits 3-15: actual status number
 271      Bits 16-27: facility number.  0 is considered "unknown"
 272      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 273                  output the message (which, for random codes, just looks ugly)
 274
 275      So, what we do here is to change 0 to 1 to get the default success status,
 276      and everything else is shifted up to fit into the status number field, and
 277      the status is tagged as an error, which I believe is what is wanted here.
