title: Error with ansible backslash in replace
body: <p>I am trying to replace a pattern with a string containing a backslash </p>
  
  <pre><code>- name: Replace test
         replace: dest=/tmp/test
         regexp="test"
         replace="test, \"
  </code></pre>
  
  <p>I get the following error in ansible:</p>
  
  <pre><code> The error appears to have been in '/home/deployer/ansible/roles/test/tasks/configuration.yml': line 11, column 3, but may
  be elsewhere in the file depending on the exact syntax problem.
  
  The offending line appears to be:
  
  
  - name: Replace test
    ^ here
  </code></pre>
