* src/copy.c (copy_internal): Omit the group- or other-writeable permissions when creating a directory, to avoid a race condition if the special mode bits aren't right just after the directory is created. * src/cp.c (make_dir_parents_private): Likewise. * tests/cp/parent-perm-race: Test for the "cp --preserve=mode" race fix in copy.c.
