title: How to add white space in the comment in Doxygen
body: <p>I was wondering is there any way to insert white space in the comment in html of Doxygen? I searched online and Doxygen manual, but I couldn't find anything to do that.</p>
  
  <p>For example, I am trying to add comment as following:</p>
  
  <pre><code>//!   motor_id,          motor direction,   accel,     min veloc,     max veloc\n
  //!   GAUGE_MOTOR_1,     CLOCKWISE,         100,       1,             360\n
  //!   GAUGE_MOTOR_2,     CLOCKWISE,         100,       1,             360\n
  //!   GAUGE_MOTOR_3,     CLOCKWISE,         100,       1,             360\n
  //!   GAUGE_MOTOR_4,     CLOCKWISE,         100,       1,             360\n
  //!   GAUGE_MOTOR_5,     CLOCKWISE,         400,       200,           350\n
  </code></pre>
  
  <p>But the html output shows the result like this</p>
  
  <pre><code>motor_id, motor direction, accel, min veloc, max veloc
  GAUGE_MOTOR_1, CLOCKWISE, 100, 1, 360
  GAUGE_MOTOR_2, CLOCKWISE, 100, 1, 360
  GAUGE_MOTOR_3, CLOCKWISE, 100, 1, 360
  GAUGE_MOTOR_4, CLOCKWISE, 100, 1, 360
  GAUGE_MOTOR_5, CLOCKWISE, 400, 200, 350
  </code></pre>
  
  <p>The white space between two words will be shrinked to one space by doxygen automatically. Is there anybody know how to fix this? That will help a lot.</p>
  
  <p>Thank you very much.</p>
