	* impunit.adb, exp_ch4.adb, s-finmas.adb: Minor reformatting.

	* exp_dist.adb (TC_Rec_Add_Process_Element): For a choice with multiple
	values, we generate multiple triples of parameters in the TypeCode.
	Bump Choice_Index for each such triple so that a subsequent default
	choice is associated with the correct index in the typecode.

	* a-cdlili.adb (Iterate): Initialize properly an iterator over a null
	container.
	(First, Last): Handle properly an iterator over a null container.

	* sem_ch10.adb (Analyze_With_Clause,Install_Withed_Unit): Abandon
	processing if we run across a node with no Scope. This can happen if
	we're with-ing an library-level instance, and that instance got errors
	that caused "instantiation abandoned".
	* sem_util.adb (Unit_Declaration_Node): Make it more robust, by raising
	an exception instead of using Assert, so it won't go into an infinite
	loop, even when assertions are turned off.

	* a-coorse.adb: Proper handling of empty ordered sets.
