title: Print branch description
body: <p>Git supports an option to the branch command called --edit-description which it states is used by "various" other commands.  One command (at least by default) that it is not used by is git branch (when used to simply list the local branches).  Is there a way to get git branch to show the branch descriptions (the verbose option looks like it just adds the last commit on the branch)?</p>
  
  <p>To be clear, I'd like something like the following</p>
  
  <pre><code>&gt; git branch
  * master      I am the alpha and the omega
    bugfix1     This is the fix to that thing
    future      Transition to the new architecture
  </code></pre>
