 357                The important thing to know is that odd numbers are considered
 358                good, while even ones are considered errors.
 359      Bits 3-15: actual status number
 360      Bits 16-27: facility number.  0 is considered "unknown"
 361      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 362                  output the message (which, for random codes, just looks ugly)
 363
 364      So, what we do here is to change 0 to 1 to get the default success status,
 365      and everything else is shifted up to fit into the status number field, and
 366      the status is tagged as an error, which I believe is what is wanted here.
