CC Mode 5.31 (C++); Patch for template syntax identification

[David A. <da...@bo...>]

The enclosed patch allows me to format my templates perfectly!

template <
    class T
  , class U
  , class R
  , class U
  , template<
        class F
      , class H
      , class G
    >::type
  , class U
    = std::auto_ptr<
          std::vector<int,
                      allocator<
                          int
                      >
          >
      >,
  , groot
>
struct foo
{
    typedef typename foo<
        bar
    >::template baz<
        mumble, bag, floot
    >::type boo;
};
