[PATCH][RFC] some emacs like keybidings for grub 0.93

[Daniele Bellucci]

Hi All,
i've just cleaned my patch, let me show you:

this little patch add the following emacs like keybindings:
- C-SPC set a marker
- C-w   move text from marker to current position(or viceversa) in kill_buf

Patch looks good to me....
i've patched Changelog too.

Feedbacks are much appreciated!

Tnx!
