        Patch #6210.  Reviewed by John Darrington.

        * ascii.c: Implement ability to resize output device parameters to
        fit terminal window size as it changes.
        (struct ascii_driver_ext): New members `auto_width',
        `auto_length'.
        (ascii_open_driver): Initialize new members, call
        update_page_size.
        (update_page_size): New function to update device size.
        (handle_option): Support new "auto" setting for length, width.
        (ascii_open_page): Call update_page_size.

Wed Jul 12 21:03:37 2006  Ben Pfaff  <blp@gnu.org>

        * table.c (tab_natural_width): Get rid of warning on empty column,
        which tended to just trigger false positives because we handle
        joined cells so badly.  We need a real fix, and the warning is not

Sat Mar  4 13:48:16 2006  Ben Pfaff  <blp@gnu.org>

        We didn't provide a way to define these macros, so obviously

        * html.c: Don't test for NO_HTML.

        * postscript.c: Don't test for NO_POSTSCRIPT.
