Log message:
        Add extension to divert builtin.
        * modules/m4.c (builtin_divert): Immediately divert second
        argument.
        * m4/output.c (m4_output_text): Allow 0 length.  Fixes regression
        from two days ago.
        (m4_shipout_text): Short-circuit on zero length.
        * tests/freeze.at (loading format 2): Expand test to catch
        regression.  Also check out-of-range version.
        * tests/builtins.at (divert): Expand test to check corner cases
        of extension.
        * NEWS: Document the extension.
