Don't open files with O_NONBLOCK or O_APPEND.
Open with O_TRUNC only if --overwrite; otherwise, use O_EXCL to avoid
overwriting them. Pass only rwxrwxrwx permissions to `open' and `mkdir',
minus the current umask. Keep track of intermediate directories made,
to avoid looping when making x/../x when x doesn't exist; the
earlier code solved this in a different way that didn't fit well
