Thanks for feedback.

The approach I took for the new grammar rules was inspired by previous commits,
such as de7531a971b, which introduced support for 'FORCE QUOTE '*''. In that
case, a new separate grammar rule was crafted.

Not sure what you mean with it being "too cute", but maybe you think it's a bit
verbose with another grammar rule and it would be better to integrate it into
the existing one?

Example:

| DELIMITER opt_as (Sconst | NONE)
{
if ($3 == NONE)
$$ = makeDefElem("delimiter", (Node *) makeString("\0"), @1);
else
$$ = makeDefElem("delimiter", (Node *) makeString($3), @1);
}
