I think this is just slightly mis-worded -- Andrew's interpretation is
the prevailing one.  That is, no brace for:

  if (blah)
     function_call (spanning,
                    multiple,
                    lines);

... but do have braces for:

  if (blah)
    {
      /* Just a comment.  */
      anything ();
    }

I agree the patch is good.  I think a test case would be good to have,
unless for some reason it's difficult to write one.
