Bug#569678: grub-pc: does not clear serial console

| Package: grub-pc
| Version: 1.98~20100115-1
| Severity: normal
| 
| grub 1 used to have a serial output that asked you to press a button at
| which point it would put you into the menu and you could walk around and
| edit.  grub 2 seems not to ask you to press a button, and when I do, it
| fails to repaint the window, leading to something that looks like:

Ok, I think I understand what's going on:

- machine starts booting, grub starts and sends the «clear screen»
  escape sequence
- I connect to the serial console (through libvirt)
- libvirt doesn't have a backlog, so I end up never getting the clear
  screen command and so grub is much less usable.

I'm not sure what's the right way to fix it, but the current state of
affairs is fairly suboptimal.
