[PATCH] grub-core/kern/corecmd: Quote variable values when displayed by the set command

[Glenn Washburn <development@efficientek.com>]

Variable values may contain spaces at the end or newlines. However, when
displayed without quotes this is not obvious and can lead to confusion as
to the actual contents of variables.
