Github - automatically merge base branch into pull request?
<p>Does Github provide a facility to automatically merge the <em>base</em> branch into a pull request? In a development team following a gitflow branching workflow, it would be useful to see what the result of "Merge Pull Request" is in the <strong>PR diff</strong>.</p>

<p>Example: Two feature branches were created based on master at the same time.</p>

<ul>
<li>Branch1: committed a change to readme and it's pulled into master via
PR.</li>
<li>Branch2: committed a change to readme, raised a pull request
(PR#3), and the diff doesn't show the line that was added with the
branch1 pull request.</li>
</ul>
