     *   ncols:     Number of columns per line defaults to 80.
     *
     *   per_line:  If this field has a positive value then every Nth element
     *              will be printed at the beginning of a line.
     *
     *   pre:       Each line of output contains an optional prefix area
     *              before the data. This area can contain the index for the
     *              first datum (represented by `%s') as well as other
     *              constant text.  The default value is `%s'.
     *
     *   1st:       This is the format to print at the beginning of the first
     *              line of output. The default value is the current value of
     *              `pre' described above.
     *
     *   cont:      This is the format to print at the beginning of each line
     *              which was continued because the line was split onto
     *              multiple lines. This often happens with compound
     *              data which is longer than one line of output. The default
     *              value is the current value of the `pre' field
     *              described above.
     *
     *   suf:       This character string will be appended to each line of
     *              output.  It should not contain line feeds.  The default
     *              is the empty string.
     *
     *   sep:       A character string to be printed after every line feed
     *              defaulting to the empty string.  It should end with a
     *              line feed.
     *
     *   multi_new: Indicates the algorithm to use when data elements tend to
     *              occupy more than one line of output. The possible values
     *              are (zero is the default):
     *
     *              0:  No consideration. Each new element is printed
     *                  beginning where the previous element ended.
     *
     *              1:  Print the current element beginning where the
     *                  previous element left off. But if that would result
     *                  in the element occupying more than one line and it
     *                  would only occupy one line if it started at the
     *                  beginning of a line, then it is printed at the
     *                  beginning of the next line.
     *
     *   multi_new: If an element is continued onto additional lines then
     *              should the following element begin on the next line? The
     *              default is to start the next element on the same line
     *              unless it wouldn't fit.
     *
     * indentlevel: a string that shows how far to indent if extra spacing
     *              is needed. dumper uses it.
