Agreed.  However, I think by far the majority of people using rethrow aren't 
intending to do it outside of a handler.  Thus I believe a warning would be 
helpful to people accidentally doing

	void foo()
	{
	...
	  try {
		// ... something ...
	    throw;
	  }
	  catch (const A&)
	  {
		// do the work here
	  }
	...
	}

or somesuch.   Right now the misplacement of the rethrow goes unmentioned 
until you end up aborting at runtime thru terminate().
