	* sigc++/macros/signal.h.m4: Make all operator--() methods 
	return by reference, like the operator++() methods. 
	Bug #304402 from John Profic.

This is the libsigc-2-0 branch, for maintenance of libsigc++ 2.0.
API/ABI-compatible API-addition happens in the HEAD branch.

	* sigc++/functors/slot_base.cc: 
	slot_base::disconnect(): Set call_ to 0, 
	to invalidate the slot, even if parent_ is 0. 
	I think parent_ is, for instance, a signal, but 
	disconnect should still work on a slot that is not 
	connected to a signal, because a slot can be invoked 
	directly.
	Fixes bug #311057 from James Lin.

	* tests/test_slot_disconnect.cc: Added test 
	case from bug #311057.

	* sigc++/adaptors/macros/exception_catch.h.m4: Make member
	exception_catch_functor<T_functor, T_catcher, void>::catcher_
	public so that it can be accessed by visit_each()
	(bug fixed for generalization on 2004-11-06)
