* NEWS: rm no longer fails to remove an empty, unreadable directory
* src/remove.c (remove_cwd_entries): If we can't open a directory,
and the failure is not being ignored, try to remove the directory
with rmdir (aka unlinkat-with-AT_REMOVEDIR), in case it's empty.
Problem report and test case from Paul Eggert in
<http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/7425>.
* tests/rm/empty-inacc: New test, for the above.
