	* decl.c (maybe_process_template_type_declaration): Handle enums.
	(start_enum): Don't check for primary-template enum declarations
	here.
	(finish_enum): Clean up, document.  Make sure template enum
	constants get the correct type.
	(build_enumerator): Copy initializers for template enumerations,
	too.
	(grok_enum_decls): Document.
	* lex.c (do_identifier): Document use of LOOKUP_EXPR a bit
