Hi,

  attached patch modifies mke2fs to always create lost+found with at least
two directory blocks. I think this could make sence not only for testing
but as a sanity check that 64KB support works for general e2fsprogs if
someone decides to use it...

                                                                Honza

Make sure lost+found has always at least 2 disk blocks. This will provide at
least elementary test that we have not screwed-up support for 64KB blocks since
the second directory block will be empty.
