title: Reflowing comment blocks with vim
body: <p>I'm cleaning up someone else's code and working with vim.  I'd like to reflow the comments so that they're formatted consistently.</p>
  
  <p>For example:</p>
  
  <pre><code>    # one two three four five six seven
      # eight nine
      # ten eleven twelve thirteen fourteen
      # fifteen sixteen seventeen 
      # eighteen
      # nineteen
  </code></pre>
  
  <p>Would become:</p>
  
  <pre><code>    # one two three four five six seven eight nine ten eleven 
      # twelve thirteen fourteen fifteen sixteen seventeen
      # eighteen nineteen
  </code></pre>
  
  <p>So, a workflow that would easily uncomment the code, reflow the paragraph and then re-comment the code with the indentation preserved.  If there is an existing plugin which does exactly this, that would be great.</p>
