+       Fix permissions bugs with setgid directories etc. (Bug#13125)
+       * files.el (backup-buffer): Don't rely on 9th output of
+       file-attributes, as it's now a placeholder.  Instead, use the new
+       optional arg of file-ownership-preserved-p.
+       (file-ownership-preserved-p): New optional arg GROUP.
+       Fix mishandling of setuid directories that would cause this
+       function to return t when it should have returned nil.
+       Document what happens if the file does not exist, and when
+       it's not known whether the ownership will be preserved.
+       * net/tramp-sh.el (tramp-sh-handle-file-ownership-preserved-p):
+       Likewise.
+       (tramp-get-local-gid): Use group-gid for integer, as that's
+       faster and more reliable.
