I might be mistaken (entirely possible!), but this behavior seems
to violate POSIX volume 3 chapter 2 section 2.13.3, which states
in part that

	Specified patterns shall be matched against existing filenames
	and pathnames, as appropriate. Each component that contains a
	pattern character shall require read permission in the directory
	containing that component. Any component, except the last, that
	does not contain a pattern character shall require search permission.
