    tmac/tests/an-old_X-register-works.sh: Rewrite.
    
    * tmac/tests/an-old_X-register-works.sh: Rewrite.  Increase test
      coverage and stop assuming that -rcR=1 and -rX=anything is a supported
      combination.  (Continuous rendering is supposed to suppress the
      printing of page numbers anyway.)
