title: How can I truncate ${level} in nlog layout to a single character?
body: <p>In the log I would like:</p>
  
  <pre><code>...D...
  </code></pre>
  
  <p>instead of </p>
  
  <pre><code>...Debug...
  </code></pre>
  
  <p>Same of course for Info, Warn, etc.  I have tried <code>${level[0]}</code> and other variations for the layout, no luck.</p>
