commit c79cd3b3a40bbcea12f869fee83c021fc6c8bf90
Author: Peter Avalos <pavalos@dragonflybsd.org>

    sh: Fix two bugs with case and exit status:
    
    * If no pattern is matched, POSIX says the exit status shall be 0 (even if
      there are command substitutions).
    * If a pattern is matched and there are no command substitutions, the first
      command should see the $? from before the case command, not always 0.
