[Bug 1278145] [NEW] Misleading/Incorrect "Warning: Setting GRUB_TIMEOUT to a non-zero value..."

[TJ]

Public bug reported:

# update-grub
Generating grub configuration file ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.
Found linux image: /boot/vmlinuz-3.13.0-8-generic
Found initrd image: /boot/initrd.img-3.13.0-8-generic
done

# grep GRUB_TIMEOUT= /etc/default/grub
GRUB_TIMEOUT=0

The warning actually refers to the value of GRUB_TIMEOUT_BUTTON (since
both values are passed to the make_timeout() function)

# grep GRUB_TIMEOUT /etc/default/grub
GRUB_TIMEOUT_BUTTON=2
GRUB_TIMEOUT=0

** Affects: grub2 (Ubuntu)
