249 
250      Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
251                The important thing to know is that odd numbers are considered
252 	       good, while even ones are considered errors.
253      Bits 3-15: actual status number
254      Bits 16-27: facility number.  0 is considered "unknown"
255      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
256                  output the message (which, for random codes, just looks ugly)
257 
258      So, what we do here is to change 0 to 1 to get the default success status,
259      and everything else is shifted up to fit into the status number field, and
260      the status is tagged as an error, which I believe is what is wanted here.
