title: How can I check which commits have not been pushed to origin?
body: <p>I have made commits to my local branch (let's just say master) and have 'git pull'd down changes that others have made. When I run a 'git status', I see something like:</p>
  
  <pre><code># Your branch is ahead of 'origin/master' by 4 commits.
  </code></pre>
  
  <p>How can I see a list of the four commits that I have made that have yet to be pushed to origin?</p>
