Log message:
        * doc/m4.texinfo: Trailing '@comment' doesn't format nicely in
        TeX, so recognize '@w{ }' instead.  Likewise, @code{_name} at the
        end of a TeX line splits incorrectly.
        (Foreach, Improved foreach): Write these sections, borrowing ideas
        from CVS head and from m4sugar.
        * checks/get-them: Accomodate new way to show trailing space in
        examples.
        * examples/foreach.m4: Make usable in documentation.
        * examples/foreachq.m4: New file.
        * examples/foreachq2.m4: New file.
        * examples/foreach2.m4: New file.
        * NEWS: Document the documentation updates.
