the problem is that it's not always an error when grub_errno is set,
for example, the test command use it to report whether or not two
strings equals.

how about script_init for the old script, and script here.

yes, the grub_script_lexer_record_start is in menuentry.

in the old implementation,
commandblock: '{'
{
grub_script_lexer_ref (state->lexerstate);
}
newlines commands '}'
{
grub_script_lexer_deref (state->lexerstate);
grub_script_lexer_record_start (state->lexerstate);
$$ = $4;
}
;
menuentry: "menuentry" argument newlines commandblock
{
char *menu_entry;
menu_entry = grub_script_lexer_record_stop
(state->lexerstate);
$$ = grub_script_create_cmdmenu (state, $2, menu_entry, 0);
}
it calls grub_script_lexer_record_start in commandblock, and
grub_script_lexer_record_stop in menuentry, but now it's both inside
menuentry. i think it's better this way. besides, if you use
commandblock alone in old implemenation, it will cause problem becuase
there is no matching grub_script_lexer_record_stop.

I didn't include the fix on the lexer, for example. ${AA}${BB} should
expand to one token instead of two. I think it's better to use a
separate patch.
