Bug#1051832: grub-efi-amd64: grub menu not shown on boot after upgrade to 2.12~rc1-9

[alban.browaeys at gmail.com]

I nailed down that the echo (even of an empty string) has to be before 
"terminal_output gfxterm". Once it is after the "terminal_output
gfxterm" instruction, the menu and background do not shows up.

Note: I also tried "GRUB_TIMEOUT_STYLE=menu" in /etc/default/grub
followed by update-grub and it did not help with this issue.

Cheers
Alban
