title: Are there any downsides to enabling git rerere?
body: <p>I've read various things about git's <code>rerere</code> feature, and I'm considering enabling it.</p>
  <blockquote>
  <p>The <code>git rerere</code> functionality is a bit of a hidden feature. The name stands for <strong>“reuse recorded resolution”</strong> and, as the name implies, it allows you to ask Git to remember how you’ve resolved a hunk conflict so that the next time it sees the same conflict, Git can resolve it for you automatically.</p>

  <p>But I haven't seen anyone mention any possible problems that could arise while using <code>rerere</code>.</p>
  <p>I have to assume there is a downside, or it would probably be enabled by default. So is there any downside to enabling rerere? What potential problems can it cause that would not otherwise occur?</p>
