title: Multiline strings that don't break indentation
body: <p>According to <a href="https://twitter.com/esdiscuss/status/512420829628362752" rel="noreferrer">this esdiscuss discussion</a>, it is possible in ECMAScript 6 to define multiline strings without having to place subsequent lines of the string at the very beginning of the line.</p>
  
  <p><a href="http://esdiscuss.org/topic/multiline-template-strings-that-don-t-break-indentation#content-11" rel="noreferrer">Allen Wirfs-Brock’s post</a> contains a code example:</p>
  
  <pre><code>var a = dontIndent
          `This is a template string.
           Even though each line is indented to keep the
           code neat and tidy, the white space used to indent
           is not in the resulting string`;
  </code></pre>
  
  <p>Could someone explain how this can be achieved? How to define this <code>dontIndent</code> thing in order to remove the whitespace used for indentation?</p>
