 346                The important thing to know is that odd numbers are considered
 347                good, while even ones are considered errors.
 348      Bits 3-15: actual status number
 349      Bits 16-27: facility number.  0 is considered "unknown"
 350      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 351                  output the message (which, for random codes, just looks ugly)
 352
 353      So, what we do here is to change 0 to 1 to get the default success status,
 354      and everything else is shifted up to fit into the status number field, and
 355      the status is tagged as an error, which I believe is what is wanted here.
