title: Doxygen link to const function
body: <p>I've got the following function prototype:</p>
  
  <pre><code>bool key_pressed(enum key key) const;
  </code></pre>
  
  <p>I documented it using doxygen. Now I have an overloaded version of that function that does the same, so I wanted to copy the doxygen comment like this:</p>
  
  <pre><code>/// @copydoc key_pressed(enum key) const
  bool key_pressed(char key) const;
  </code></pre>
  
  <p>This does not work, I get the following warning from doxygen:</p>
  
  <pre><code>Warning: target key_pressed(enum key) const of \copydoc command not found
  </code></pre>
  
  <p>If I remove the <em>const</em> from key_pressed(enum key) and from the @copydoc line, it works.</p>
  
  <p>Did I specify the modifier correctly in my copydoc command?</p>
