title: display a link in truncate smarty
body: <p>In smarty we can use this to shorten the text output:</p>
  
  <pre><code>{$articleTitle}
  {$articleTitle|truncate}
  {$articleTitle|truncate:30}
  {$articleTitle|truncate:30:""}
  {$articleTitle|truncate:30:"---"}
  {$articleTitle|truncate:30:"":true}
  {$articleTitle|truncate:30:"...":true}
  {$articleTitle|truncate:30:'..':true:true}
  </code></pre>
  
  <p>the results will be like this:</p>
  
  <pre><code>Two Sisters Reunite after Eighteen Years at Checkout Counter.
  Two Sisters Reunite after Eighteen Years at Checkout Counter.
  Two Sisters Reunite after...
  Two Sisters Reunite after
  Two Sisters Reunite after---
  Two Sisters Reunite after Eigh
  Two Sisters Reunite after E...
  Two Sisters Re..ckout Counter.
  </code></pre>
  
  <p>What I want to display is this : "<code>... &lt;a href="{$url}"&gt;read more&lt;/a&gt;</code>" 
  when you apply it to the code, it would be something like this : </p>
  
  <pre><code>{$articleTitle|truncate:30:"... &lt;a href="{$url}"&gt;read more&lt;/a&gt;":true}
  </code></pre>
  
  <p>but this does not work. How can I make it work?</p>
