title: Customize doxygen formatting of pure virtual function
body: <p>Let's say I have a C++ class with a pure virtual function like this:</p>
  
  <pre><code>class Thing {
  public:
      virtual void doStuff(int a, int b) = 0;
  }
  </code></pre>
  
  <p>When doxygen runs over this, you get a line in the (HTML) docs that looks like:</p>
  
  <blockquote>
    <p>virtual void doStuff(int a, int b)=0</p>
  </blockquote>
  
  <p>The thing is, this is technically correct but I think it looks really ugly to have that '=0' at the end there. The fact that this function is pure virtual (or even that it is virtual) does not matter to my customers. </p>
  
  <p>So is there any way to tell doxygen to hack off that '=0'? Or more generally to customize this output?</p>
