title: Django add 1 to pages.current before printing it (django-endless-pagination)
body: <p>I have a variable, pages.current.  I want to display this variable + 1 on a web page.  (i.e. if pages.current is 1, I want it to show 2; etc).</p>
  
  <p>My current code:</p>
  
  <pre><code>&lt;p&gt;Page {{ pages.current|add:"1" }} &lt;/p&gt;.  
  </code></pre>
  
  <p>Unfortunately, this doesn't seem to be working (that code simply displays pages.current's value, without the +1) and I don't understand why.  Thanks!</p>
