<p><b>Addresses: filesys.ts</b></p>
<p>The postconditions for the copy/move constructor for path are shown as "empty()".
This appears to have been incorrectly copied from the default ctor.</p>

<p>Remove the 'postconditions' clause from the copy/move ctor.</p>

<p><i>[2014-02-07, Beman Dawes suggests wording]</i></p>




<p id="res-2614"><b>Proposed resolution:</b></p>
    <p>
      <i>Change 8.4.1 [path.construct]:</i>
    </p>
    <blockquote>
    <pre>
      path(const path&amp; p);
      path(path&amp;&amp; p) noexcept;
    </pre>
    <blockquote>
      <p>
        <i>Effects:</i> Constructs an object of class <code>path</code> with <code>
          pathname
        </code> having the original value of <code>p.pathname</code>. In the
        second form, <code>p</code> is left in a valid but unspecified state.
      </p>
      <p>
        <del><i>Postconditions:</i> empty().</del>
      </p>
