Bind "accept" update

Peter,
  I've got a small patch to Boost.Bind that changes the visitor calls in 
bind_T<...>.accept(v) from:
  v(a1);

to 
  v(remove_bind_specific_stuff(a1));

So, for instance, the visitor won't see, e.g., boost::_bi::value<T> but would 
just see <T> instead. reference_wrapper<T>, however, is passed through 
unchanged because that is now standard for Boost.

I need the changes to keep the Signals library less coupled to Boost.Bind. 
Okay to commit?
