Log message:
        * checks/get-them: Make filtering easier.
        * checks/check-them: Filter non-input lines, so line counts are
        more realistic in the documentation, and so changeword tests work
        even when dnl is disabled.
        * doc/m4.texinfo: Adjust example line numbers.  Clean up
        front-matter, following autoconf's example.
        (Changeword): Enable tests, skipping if changeword not supported.
        (Define, Defn, Ifelse): Backport more examples from head.
        (Input processing, Answers): New nodes, backported from head.
        (Include): Expand test to cover empty filename.
        (Undivert): Add test of undivert(0).
