title: How to compare two different commits on the same branch in github?
body: <p>Comparing histories on the same branch is very confusing for me on GitHub. I struggle with this regularly:</p>
  
  <p>If I use <code>compare/master</code> in the URL after the GitHub repo name, I can compare against other branches in the repo based on the options in the drop-down menus.</p>

  <p>However, I usually want to compare several commits on master. </p>
  
  <p>How is this easily done? Could I get a more clear example? </p>
