Bug#464839: grub-pc: update-grub does not export user defined variables

[Martin Haaß]

Package: grub-pc
Version: 1.96+20080203-1
Severity: normal
Tags: patch

User defined variables in /etc/default/grub are not exported to the scripts
run by update-grub. This is a little sed hack to export all variables used
in /etc/default/grub.
