	* sem_ch6.adb (Analyze_Expression_Function): Code cleanup:
	if the expression function is not a completion, create a
	new specification for the generated declaration, and keep the
	original specification in the generated body. Shorter code also
	ensures that proper warnings are generated for unused formals
	in all cases.

	* tree_io.ads: Update ASIS_Version_Number because of the changes
	in the tree structures for expression functions.
