title: How to provide git revision/version for useful bug report?
body: <p>I compile and test git versions of open source software. When I find bugs, I want to write concise, useful reports.</p>
  
  <p>How do I provide useful git commit or "version" information in a bug report, so that developers immediately know what "revision" I have tested?</p>
  
  <p>I know of</p>
  
  <pre><code>git rev-parse HEAD
  </code></pre>
  
  <p>which creates output like</p>
  
  <pre><code>a2e2e93c85b2c7431c365fd52b4456d28db9d531
  </code></pre>
  
  <p>which might not be too useful because it's not easily readable to humans.</p>
