title: Linebreak a raw string
body: <p>I'm looking for a good way to linebreak long raw strings in python.
  The reason for that is, that I'm often using windows path together with <code>pathlib</code>s <code>Path</code>, as this allows me for convenient copy pasting on both windows and *nix like this:</p>
  
  <pre><code>from pathlib import Path
  my_long_path = Path(r'C:some\very\long\path')
  </code></pre>
  
  <p>Now naturally, filepaths can get quite long and for better code formatting I sometimes want to linebreak raw strings. </p>
  
  <p>What doesn't work is tripple quotes, because of the linebreak symbol:</p>
  
  <pre><code>a = r'''some\
  very\long\path'''
  
  --&gt; 'some\\\nvery\long\path'
  </code></pre>
  
  <p>So the only option I know is:</p>
  
  <pre><code>a = r'some\'\
  r'very\long\path'
  </code></pre>
  
  <p>It works but feels a little un-pythonic. Is there a better way to do this?</p>
