title: Show git ahead and behind info for all branches, including remotes
body: <p>On a github project you can go to a /branches page and se pretty graphs like this one that for each branch show how far behind and how far ahead each branch is with respect to master.</p>
  
  <p><img src="https://i.stack.imgur.com/aFmCc.png" alt="git branch ahead behind"></p>
  
  <p>Is there a command line tool that does something similar? Something that works with remotes as well?  For example,</p>
  
  <pre><code>git branch -v -v
  </code></pre>
  
  <p>is close to what I am looking for, but only works for local branches.</p>
