+ * lib/mkdir-p.c (make_dir_parents): Close a race condition that
+ occurs when "mkdir -m foo" creates a setgid directory that is (1)
+ writeable to group or other and (2) is intended to have a special
+ mode bit that is set or cleared. In such a case, the directory
+ should be neither group- nor other-writeable until the special
+ mode bits are right.
