New Revision: 224854
URL: http://svn.freebsd.org/changeset/base/224854

Log:
  MFC r222716: sh: Fix $? in heredocs on simple commands.
  
  The patch is slightly different because redirected compound commands are
  handled differently in stable/8 (no separate function, redirection errors
  are fatal).
