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.
