title: clang-format: add spaces after ( and before ) only for ControlStatements(for/if/while...)
body: <p>I'm using clang-format to format code.
  I would like to know if it is possible to add space after ( and before ) only for control statements like for/while/if.</p>
  
  <p>I have tested SpacesInParentheses but it applies to all parentheses:</p>
  
  <pre><code>for( int i=0; i&lt;10; i++ )
  {
    fct( a, b );
  }
  </code></pre>
  
  <p>I would like something like this:</p>
  
  <pre><code>for( int i=0; i&lt;10; i++ )
  {
    fct(a, b);
  }
  </code></pre>
