title: Create git patch from specific commits
body: <p>Let's say you have commits on Branch A:</p>
  
  <pre><code>1
  2
  3X
  4
  5X
  6
  7
  </code></pre>
  
  <p>And you want to create a patch from commits 1,2,4,6. I think it's possible using 3 patches:</p>
  
  <pre><code>git format-patch -2 3X --stdout &gt; first.patch
  git format-patch -1 5X --stdout &gt; second.patch
  git format-patch -1 7  --stdout &gt; third.patch
  </code></pre>
  
  <p>But is it possible using a single patch?</p>
