No scrolling for long input lines

[Andy Goth <unununium@aircanopy.net>]

(I said I would research this some more, but I haven't had a chance, and I won't get one for a couple days, so rather than wait, I am simply posting what I know.)

In GRUB 1.96, typing an input line longer than the screen is wide does not cause the screen to scroll.  Effectively this means once I get to the bottom of the screen, anything I type that's longer than 80 characters (less prompt) I have to type blind.  Aside from not being able to see what I type, everything behaves normally.

My GRUB configuration is plain vanilla.  GRUB's on a FAT12 floppy read in using biosdisk, there's no grub.cfg file, and I directly type in insmod, ls, linux, initrd, boot, and all that jazz.  I haven't made any modifications to the source, and I'm using the 1.96 release I found on alpha.gnu.org.  I have the biosdisk and fat modules compiled into the GRUB image.
