	* exp_ch5.adb (Expand_N_Case_Statement): If a choice is a
	subtype indication and the case statement has only two choices,
	replace subtype indication with its range, because the resulting
	membership test cannot have a subtype indication as an operand.

	* exp_ch3.adb: Update comments, minor reformatting.
