Description:
Remove unsightly widows by adding a non-breaking space between the last two words in a string.
Apply the template with param named `text` and use `normalize space` to remove any extra space at the end of the string.
<xsl:call-template name="widont-title">
<xsl:with-param name="text" select="normalize-space(fields/title)" />
</xsl:call-template>
If the combined length of two last words is longer than the character length defined in the `maxlen` parameter, the non-breaking space is not added. This prevents the opposite of widows: orphans. Feel free to adjust that parameter.
