title: How to show log between current branch and its remote counterpart
body: <p>Sometimes after fetching from remote repository I see my branch is behind:</p>
  <pre><code>&gt; git status
  On branch develop
  Your branch is behind 'origin/develop' by 7 commits, and can be fast-forwarded.
    (use &quot;git pull&quot; to update your local branch)
  </code></pre>
  <p>Before updating my local branch I would like to see the log of what I'm about to get. I can do it using</p>
  <pre><code>&gt; git log develop..origin/develop
  </code></pre>
  <p>Since I'm already on the <code>develop</code> branch, is there a way to do the above with less typing?  That is, without providing local and remote branch names?</p>
  <p>This would be especially useful since I often switch to feature branches and would like to see such logs for those, too.</p>
