title: Inline editing with Rails gem 'best_in_place' - bug: new lines are lost after edit on textarea
body: <p>I am using <a href="https://github.com/bernat/best_in_place#readme" rel="noreferrer">best_in_place</a> gem to do some inline editing in a Rails app.</p>
  
  <p>One of the property of my object is of type <code>text</code>, and I want it to be edited in a text area, so I did this:</p>
  
  <pre><code>&lt;%= best_in_place @myobject, :description, :type =&gt; :textarea %&gt;
  </code></pre>
  
  <p>It works, but when not being edited, all returns (\n) are removed.</p>
  
  <p>I tried using simple_format, by adding <code>:display_with =&gt; :simple_format</code> to the options passed to best_in_place:</p>
  
  <pre><code>&lt;%= best_in_place @myobject, :description, :type =&gt; :textarea, :display_with =&gt; :simple_format %&gt;
  </code></pre>
  
  <p>When not being edited, the new lines are displayed as expected. But the click to enter edition is broken, and a new dash is added above. Clicking it display a textarea box, but it is empty, and the text entered there is not saved back to my object.</p>
  
  <p>The content saved in my property is just plain text, it does not contain any html.</p>

  <p>This issue (and patch) seemed related to my problem: <a href="https://github.com/bernat/best_in_place/pull/111" rel="noreferrer">https://github.com/bernat/best_in_place/pull/111</a><br>
  However, when applying the patch (manually, to the file <code>.../gems/best_in_place-1.0.6/spec/spec_helper.rb</code>), I still have the same problem.</p>
