title: When I "git push" git now says "Create pull request for ...". Why?
body: <p>I am making changes to a project in a branch that, so far, is known to no one else but me.  However, starting recently, when I <code>git push</code> to this project, I now receive this as part of the response:</p>
  
  <pre><code>remote: Create pull request for &lt;&lt;my branch&gt;&gt;:
  remote:   https://bitbucket.org/...
  </code></pre>
  
  <p>I have no idea why Git is giving me this message, which I have never seen before.</p>
  
  <p>Even if I <em>delete</em> the remote branch (with "<code>git push origin :&lt;&lt;my branch&gt;&gt;</code>" I now <em>still</em> get this message! (I successfully <strong>deleted</strong> the branch on the remote, but the message remains)</p>
