This patch fixes an old bug when backspace key does not work in the
username login prompt. It allows BIDI type BN characters (control
chars like '\b') in the visual line. And when grub_gfxterm_putchar
recieves this line it successfully processes backspace.

Hi, I'd like to try to propose this patch again. I'm new to the open
source community, so any feedback and suggestions will be appreciated.
