Formats text into a nice paragraph format. The text is separated into words and then reassembled a word at a time using the settings of this Format object. If a word is larger than the number of columns available for formatting, then that word will appear on the line by itself.

If to_wrap is nil, then the value of #text will be worked on.

    __format(to_wrap[0])
