384
Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
385
The important thing to know is that odd numbers are considered
386
good, while even ones are considered errors.
387
Bits 3-15: actual status number
388
Bits 16-27: facility number. 0 is considered "unknown"
389
Bits 28-31: control bits. If bit 28 is set, the shell won't try to
390
output the message (which, for random codes, just looks ugly)
392
So, what we do here is to change 0 to 1 to get the default success status,
393
and everything else is shifted up to fit into the status number field, and
394
the status is tagged as an error, which I believe is what is wanted here.
