Bug#613120: to fringe and half way

[Bryan Cebuliak]

Good pickup, Roderich. But, your script  alteration   still, for me,
results   in   some   black   space    where  the   terminal   text
has   not   written. This is fixed   by editing command   lines  and
refreshing  the  terminal. I  use  a custom   background. It   does
not  have  all  the   black space like   the  Debian  supplied
desktop-grub, so  you may be not seeing the  problem completely?
