+       Fix permissions bugs with setgid directories etc. (Bug#13125)
+       * dired.c (Ffile_attributes): Return t as the 9th attribute,
+       to mark it as a placeholder.  The old value was often wrong.
+       The only user of this attribute has been changed to use
+       file-ownership-preserved-p instead, with its new group arg.
+       * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
