[PATCH] Block parameter support for GRUB script

[BVK Chaitanya]

Hi,


Attached patch adds support for block-of-commands-in-braces as a
generic parameter to any GRUB script command.  Now menuentry like
commands can be created without modifying the GRUB script grammar.

As an example, hello command is modified to take an optional BLOCK
parameter, which it stores for later use.  When it is invoked without
any parameters, it would execute recently saved BLOCK parameter's
commands (or defaults to "Hello World" if no BLOCK parameter is
saved).
