title: Why does Doxygen documentation only appear for the last of multiple adjacent groups?
body: <p>I'm trying to document several similar functions at once using Doxygen groups. I would like the functions to share the same documentation as shown in the example <a href="http://www.doxygen.nl/manual/grouping.html#memgroup" rel="nofollow noreferrer">here</a>.</p>
  
  <pre><code>// @{
  //! @brief Some documentation
  int func1(void);
  int func2(void);
  // @}
  
  // @{
  //! @brief Some other documentation
  int func3(void);
  int func4(void);
  // @}
  </code></pre>
  
  <p>However, when I run doxygen, <em>only the 2nd group</em> displays the @brief message in the HTML output. Am I doing something wrong, or is this a potential bug?</p>
  
  <p>Note, I am <em>not</em> trying to nest groups, which the doxygen documentation says is not allowed.</p>
