[move][doc] missing return type

[Akira Takahashi <faithandbrave@…>]

this code in introduction document:

template <class T> swap(T& a, T& b)
{
   T tmp(a);   // now we have two copies of a
   a = b;      // now we have two copies of b
   b = tmp;    // now we have two copies of tmp (aka a)
}

template <class T> swap(T& a, T& b)
{
   T tmp(::boost::move(a));
   a = ::boost::move(b);
   b = ::boost::move(tmp);
}

http://www.boost.org/doc/libs/1_48_0/doc/html/move/introduction.html

it seem missing return type(void). should be:

template <class T> void swap(T& a, T& b)
{
   T tmp(a);   // now we have two copies of a
   a = b;      // now we have two copies of b
   b = tmp;    // now we have two copies of tmp (aka a)
}

template <class T> void swap(T& a, T& b)
{
   T tmp(::boost::move(a));
   a = ::boost::move(b);
   b = ::boost::move(tmp);
}
