title: create branch with N-last commits
body: <p>I have cloned repository and have made some commits:</p>
  
  <pre><code>git clone ...
  git add
  git commit
  git add
  git commit
  git add 
  git commit 
  </code></pre>
  
  <p>Now I have realized that it will be better to move all my commits to another new branch. What is the best way to do it?</p>
