Bug#593242: grub-pc: zz-update-grub fails to run update-grub (quoting error)

[Will Dyson]

Package: grub-pc
Version: 1.98+20100804-2
Severity: normal


On lines 5 and 6 of /etc/kernel/postinst.d/zz-update-grub, the single-quote
character is not escaped. This prevents the substring removals from working
correctly, and the case comparison fails due to the presense of extra quote
characters.
