[RHEL only] tcsh-6.19.00-tcsh-posix-status.patch added back
    
      The patch for $tcsh_posix_status has been added back to prevent future
      regressions in RHEL, after discussion in BZ #1349179.
    
      This patch is commented out by default for Fedora, and should be only
      enabled after a new fork of RHEL is created from Fedora.
