368                The important thing to know is that odd numbers are considered
369 	       good, while even ones are considered errors.
370      Bits 3-15: actual status number
371      Bits 16-27: facility number.  0 is considered "unknown"
372      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
373                  output the message (which, for random codes, just looks ugly)
374 
375      So, what we do here is to change 0 to 1 to get the default success status,
376      and everything else is shifted up to fit into the status number field, and
377      the status is tagged as an error, which I believe is what is wanted here.
