title: How to correctly have multi line yaml strings?
body: <p>newlines on multiple lines does not seem to work out for me:</p>
  
  <p>Something like:</p>
  
  <pre><code>  intro: |
      We are happy that you are interested in
      and  
      more
  </code></pre>
  
  <p>and + more needs to be on a newline but it fails.</p>
  
  <pre><code>  intro: |
      | We are happy that you are interested in
      | and  
      | more
  </code></pre>
  
  <p>or</p>
  
  <pre><code>  intro: |
      We are happy that you are interested in \n
      and  
      more &lt;2 spaces &gt;
      another one
  </code></pre>
  
  <p>All fail.</p>
