	* sem_prag.adb (Analyze_Input_Item): Allow formal
	parameters to appear as input_items in an initialization_list
	of pragma Initializes. Encapsulation now applies to states and
	variables only (as it should). Add RM references to key errors.
	* sem_prag.adb (Set_Imported): Suppress errors
	about preceding Imports when the pragma does not come from source,
	which can happen through use of pragma Provide_Shift_Operators.
