* normal/lexer.c (grub_script_yylex): Don't filter out newlines.

	* normal/parser.y (commandblock): Defined as <cmd>.  A subroutine
	for `menuentry'.
	(script): Accept leading newlines.
	(newlines): New rule to describe 0 or more newlines.
	(commands): Accept `command' with trailing newline.  Fixed the
	order in which arguments were passed to `grub_script_add_cmd'.
	Accept commands separated by newlines.
	(function): Changed to accept newlines.
	(menuentry) Rewritten.

	* normal/script.c (grub_script_create_cmdmenu): Add new entries in
	front of the list, instead of to the end.
