     * This part is tricky. We need to make sure a few things:
     *
     *   1. GetDiskFreeSpaceEx is always called at least once for large HD.
     *        Even if skip_root() returned NULL (e.g. "C:").
     *        Note that trimslashtoend() will nullify "C:".
     *   2. GetDiskFreeSpaceEx is called with the deepest valid directory.
     *        e.g. C:\drive when the user types C:\drive\folder1\folder2.
     *        This makes sure NTFS mount points are treated properly (#1946112).
     *   3. `s' stays valid after the loop for GetDiskFreeSpace.
     *        This means there is no cutting beyond what skip_root() returns.
     *        Or `s' could be recreated when GetDiskFreeSpace is called.
     *   4. If GetDiskFreeSpaceEx doesn't exist, GetDiskFreeSpace is used.
     *   5. Both functions require a trailing backslash
     *   6. `dir' is never modified.
