title: Find out a Git branch creator
body: <p>I want to find out who created a branch.</p>
  
  <p>I am sort of able to do so with:</p>
  
  <pre><code>git branch -a | xargs -L 1 bash -c 'echo "$1 `git log --pretty=format:"%H %an" $1^..$1`"' _
  </code></pre>
  
  <p>However, this returns the last committer per branch, not necessarily the person who created the branch.</p>
