    Shrink file systems to exact size (#701075)
    
    Ext[234] file systems were being shrunk 1 KiB too small.  Ntfs and
    reiserfs file systems were being shrunk 1 byte too small.  The resultant
    file systems were ending up 1 block smaller than they could have been.
    
    This looks like an accidental leftover from when GParted use to:
    1) Shrink the file system 1 cylinder too small
    2) Shrink the partition
    3) Grow the file system to fill the partition
    Relevant commit:
    
        d663c3c277f60da2ac1785c039f25f7920a315e9
        removed cylindersize buffering during resize from the filesystems
    
    Closes Bug #701075 - Setting the backup boot sector when resizing NTFS
