	* class.c (instantiate_type): Don't treat template-ids that don't
	specify any template arguments as equivalent to ordinary
	identifiers.  Use OFFSET_REF instead of SCOPE_REF to refer to
	pointer-to-members for member templates.  Tidy slightly.
	* cp-tree.def (TEMPLATE_ID_EXPR): Revise documentation.
	* init.c (build_offset_ref): Handle template-ids like ordinary
	identifiers, for the most part, but store a TEMPLATE_ID_EXPR in the
	offset part of the OFFSET_REF.
	* typeck.c (build_unary_op): Change check for unknown types to
	look for OFFSET_REFs, not SCOPE_REFs.
