Bug#562034: grub-common: 30_os-prober fails under dash

[tony mancill]

Package: grub-common
Version: 1.98~20091221-1
Severity: important
Tags: patch


After upgrading from squeeze to sid, I am getting the following error
from the 30_os-prober script.  The dash shell doens't support the 
function keyword - the attached patch addresses the issue for me.

Thank you,
Tony
