title: Writing to a new line in a file using Commons IO?
body: <p>I know that </p>
  
  <pre><code>FileUtils.writeStringToFile(myfile.txt, "my string", true);
  </code></pre>
  
  <p>adds 'my string' to the end of myfile.txt, so it looks like</p>
  
  <pre><code>previous stringsmy string
  </code></pre>
  
  <p>But is there any way to use Commons IO to write a string to a new line in a file, to change the file to</p>
  
  <pre><code>previous strings
  my string
  </code></pre>
