 It's easy to construct a different encoding of WIF* that gives you 30
 bits of exit code. It would be stupid for that to be *against* POSIX
 rather than merely not being required.
 
 There isn't any compelling reason for NetBSD to change, but there are
 obvious reasons for any new implementation to favor such an encoding.
 
 Wouldn't exactly be the first POSIX_MISTAKE though.
