title: How can I see what I am about to push with git?
body: <p>Is there a way to see what would be pushed if I did a <code>git push</code> command?</p>
  
  <p>What I'm picturing is something like the "Files Changed" tab of Github's "pull request" feature. When I issue a pull request, I can look and see what will be pulled in if they accept my pull request: <img src="https://i.stack.imgur.com/YUZlu.png" alt="github example of aggregate changes"></p>
  
  <p>Command line is OK, but I'd prefer some sort of GUI (like the screenshot above).</p>
