# error are a non-existent file (which won't happen because
# finddepth() only calls its routine for existing files) or a file
# owned by someone else.  We can't rely on being able to chown()
# a file unless we're root, though, and if we're root, the file will
# be writable because root can write to anything.  So just punt on
# this for now.
