title: Ruby backslash to continue string on a new line?
body: <p>I'm reviewing a line of Ruby code in a pull request. I'm not sure if this is a bug or a feature that I haven't seen before:</p>
  
  <pre><code>puts "A string of Ruby that"\
    "continues on the next line"
  </code></pre>
  
  <p>Is the backslash a valid character to concatenate these strings? Or is this a bug?</p>
