title: How to checkout git state before merge?
body: <p>I merged a git branch into my master, but now I want to get the state of the code before the merge. I do not want to revert the merge. How do I do this? Running <code>git log</code> shows hundreds of commits, but doesn't list the branch, so I'm not sure how to find the commit hash. <a href="https://stackoverflow.com/questions/16974204/how-to-get-commit-history-for-just-one-branch">This answer</a> recommends running <code>git log master..</code> but this returns nothing for me.</p>
