From 76b12f000534e588e65a6d8b4a152e9e382d4f85 Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>

Subject: (struct mkdir_options): New struct. (announce_mkdir, make_ancestor):
 New functions. (main): Use them.  Adjust to mode_adjust API change.  Stick
 with umask 0.  Use make_dir_parents for all the work.
