 250
 251      Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
 252                The important thing to know is that odd numbers are considered
 253                good, while even ones are considered errors.
 254      Bits 3-15: actual status number
 255      Bits 16-27: facility number.  0 is considered "unknown"
 256      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 257                  output the message (which, for random codes, just looks ugly)
 258
 259      So, what we do here is to change 0 to 1 to get the default success status,
 260      and everything else is shifted up to fit into the status number field, and
 261      the status is tagged as an error, which I believe is what is wanted here.
