einfo.ads, einfo.adb (Default_Aspect_Component_Value): Is on base type only. 

2013-10-14  Robert Dewar  <dewar@adacore.com>

	* einfo.ads, einfo.adb (Default_Aspect_Component_Value): Is on base type
	only.
	* exp_aggr.adb (Expand_Array_Aggregate): Handle proper
	initialization of <> component.
	* exp_ch3.adb, exp_tss.adb: Minor reformatting
	* sem_ch13.adb (Default_Aspect_Component_Value, Default_Aspect_Value):
	Is on base type only.
	* sinfo.ads: Minor comment revision.

2013-10-14  Robert Dewar  <dewar@adacore.com>

	* g-decstr.adb (Decode_Wide_Wide_Character): Fix failure
	to detect invalid sequences where longer than necessary
	sequences are used for encoding.
	(Validate_Wide_Character):
	Call Decode_Wide_Character to get the above validations.
	(Validate_Wide_Wide_Character): Same fix
	* g-decstr.ads: Add documentation making it clear that the UTF-8
	implementation here recognizes all valid UTF-8 sequences, rather
	than the well-formed subset corresponding to characters defined
	in Unicode.
	(Next_Wide_Character): Remove comment about this
	being more efficient than Decode_Wide_Character (because this
	no longer the case).
	(Prev_Wide_Character): Add note that valid encoding is assumed.

2013-10-14  Robert Dewar  <dewar@adacore.com>

	* a-wichha.adb (Character_Set_Version): New function.
	* a-wichha.ads: Remove comments for pragma Pure (final RM has
	this).
	(Character_Set_Version): New function.
	* gnat_rm.texi: Update doc.
