title: How to tell flake8 to ignore comments
body: <p>I'm using flake8 in emacs in order to clean up my python code. I find it annoying to have my comments flagged as errors (<code>E501 line too long (x &gt; 79 characters)</code>). I'm wondering if anyone knows a way to kindly ask flake8 to ignore comments, both single and multi-line, but still let me know when my non-comment lines are too long? </p>
  
  <p>Thanks in advance! </p>
