302 
303      Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
304                The important thing to know is that odd numbers are considered
305 	       good, while even ones are considered errors.
306      Bits 3-15: actual status number
307      Bits 16-27: facility number.  0 is considered "unknown"
308      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
309                  output the message (which, for random codes, just looks ugly)
310 
311      So, what we do here is to change 0 to 1 to get the default success status,
312      and everything else is shifted up to fit into the status number field, and
313      the status is tagged as an error, which I believe is what is wanted here.
