[boost] [MPL] insert_range bug with empty sequences

I have found that applying insert_range to append elements to an empty
sequence has no effect. E.g., the following compiles without error on
every compiler I have tried (VC7.1, GCC 3.2, Intel 7.1 and CW8.0).

    typedef mpl::insert_range<
                mpl::list0<>,
                mpl::end< mpl::list0<> >::type,
                mpl::list<int>
            >::type result;
    BOOST_STATIC_ASSERT((size<result>::type::value == 0));

I get the same result if I use vectors instead of lists.

This looks like a bug to me.
