<code>copy_options::copy_symlinks</code> is not used (should test it before calling <code>copy_symlinks</code> in <code>copy</code>).
</p>
  <p><i>[20 May 2014 Beman Dawes provides proposed wording.]</i></p>



<p id="res-2636"><b>Proposed resolution:</b></p>
  <p>
    <i>Change 15.3 Copy [fs.op.copy]:</i>
