<para>
If the <parameter>cut_long_words</parameter> is set to &true;, the string is
always wrapped at or before the specified <parameter>width</parameter>. So if you have
a word that is larger than the given width, it is broken apart.
(See second example). When &false; the function does not split the word
even if the <parameter>width</parameter> is smaller than the word width.
