title: Format constructor member initialization with Uncrustify
body: <p>I'm using uncrustify 0.56 and I'd like to know if it's possible to format constructors like that:</p>
  
  <pre><code>MyClass::MyClass(int arg1, int arg2, int arg3) : m_arg1(arg1), m_arg2(arg2), m_arg3(arg3) {}
  
  // shall be formatted to
  
  MyClass::MyClass(int arg1, int arg2, int arg3) : 
     m_arg1(arg1), 
     m_arg2(arg2), 
     m_arg3(arg3)
  {
  }
  </code></pre>
  
  <p>I couldn't find any option. Is this possible or is there another code beautifer/tool to achieve this kind of format?</p>
  
  <p>Thanks in advance ...</p>
