	* exp_attr.adb, inline.adb, sem_attr.adb, sem_elab.adb: Minor
	reformatting.

2016-06-16  Bob Duff  <duff@adacore.com>

	* sem_util.adb (Collect): Avoid Empty Full_T. Otherwise Etype
	(Full_T) crashes when assertions are on.
	* sem_ch12.adb (Matching_Actual): Correctly handle the case where
	"others => <>" appears in a generic formal package, other than
	by itself.

2016-06-16  Arnaud Charlet  <charlet@adacore.com>

	* usage.adb: Remove confusing comment in usage line.
	* bindgen.adb: Fix binder generated file in codepeer mode wrt
	recent additions.

2016-06-16  Javier Miranda  <miranda@adacore.com>

	* restrict.adb (Check_Restriction_No_Use_Of_Entity): Avoid
	never-ending loop, code cleanup; adding also support for Text_IO.
	* sem_ch8.adb (Find_Expanded_Name): Invoke
	Check_Restriction_No_Use_Entity.

2016-06-16  Tristan Gingold  <gingold@adacore.com>

	* exp_ch9.adb: Minor comment fix.
	* einfo.ads (Has_Protected): Clarify comment.
	* sem_ch9.adb (Analyze_Protected_Type_Declaration): Do not
	consider private protected types declared in the runtime for
	the No_Local_Protected_Types restriction.
