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