misc cp-namespace.c cleanups

gdb/ChangeLog:

	* cp-namespace.c (cp_basic_lookup_symbol): Rename parameter
	anonymous_namespace to is_in_anonymous for consistency with the rest
	of the file.
	(cp_lookup_bare_symbol): Fix typo in comment.
	(cp_search_static_and_baseclasses): Ditto.
	(search_symbol_list): Use vertical space in comment better.
	(reset_directive_searched): Ditto. Fix typo.
	(cp_lookup_nested_symbol_1): Clarify contents of NESTED_NAME parameter.
