    SubjectRe: PATCH to access old-style FAT fs

    I have attached a newer, better behaving version of my patch:
    * Implements new mount option oldfat for FAT-derived filesystems.
    * Stops scanning dirs when DIR_Name[0] = 0 when oldfat is set
    * Writes a 0 to the next entry DIR_Name[0] when overwriting an entry
    which has DIR_Name[0] = 0 when oldfat is set

    It has been tested with both msdos and vfat filesystems and seems to
    work well (unlike the patch of a few days ago, which had some issues).

    Once you get around to cleaning up the code and making the
    stop-scanning-dirs-on-zero the default way, the patch can be shrunken to
    include only the third item.

    I am not convinced that the goto is always safe, and I am pretty sure
    that it works now (though not as efficient as possible, perhaps), so I
    have left that in place for now.

    Both are now implemented using the new fat_write_zero_entry function.

    Thanks for your help,
