title: org-export-as-latex adds trailing slashes
body: <p>Given this file:</p>
  
  <pre><code>#+title: test
  
  some words.
  
  /some emphasis/.
  
   /some emphasis/.
  
  /emphasis/.
  </code></pre>
  
  <p><code>org-export-as-latex</code> (emacs 23.4.1; Org-mode 6.33x) produces this:</p>
  
  <pre><code>[...]
  some words.
  
  \emph{some emphasis\}.
  
   \emph{some emphasis}.
  
  \emph{emphasis}.
  [...]
  </code></pre>
  
  <p>The compilation therefore fails.  The same is true if I use <code>*some emphasis*</code> where the markup is more than one word and and starts a new line.  Is this a known problem?   </p>
  
  <p><strong>Update:</strong></p>
  
  <p>This seems to be a problem with emacs 23.4.1's org-mode (version 6.33x), at least as installed from the repositories for Ubuntu 12.10.  With emacs 24.1.1 (and 7.8.11), the problem disappears.  ... So this question is closed for me, but maybe there is still a solution for people still using emacs &lt; 24.1.1</p>
