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