title: How to preview git-pull?
body: <p>Is it even possible?</p>
  
  <p>Basically, there's a remote repository from which I pull using just:</p>
  
  <pre><code>git pull
  </code></pre>
  
  <p>Now, I'd like to preview what this pull would change (a diff) without touching anything on my side. The reason is that thing I'm pulling might not be "good" and I want someone else to fix it before making my repository "dirty".</p>
