title: Surround with quotation marks
body: <p>How is it possible in Eclipse JDT to convert a multiline selection to String. Like the following</p>
  
  <p>From:</p>
  
  <pre><code>xxxx
  yyyy
  zzz
  </code></pre>
  
  <p>To:</p>
  
  <pre><code>"xxxx " +
  "yyyy " +
  "zzz"
  </code></pre>
  
  <p>I tried the following template </p>
  
  <pre><code>"${line_selection}${cursor}"+
  </code></pre>
  
  <p>but that way I only get the whole block surrounded not each line separately. How can I achieve a multiline processing like commenting the selected block?</p>
