A small bug in gram.y

Hi,
In the gram.y, under a_expr rule
under the subrule "a_expr NOT SIMILAR TO a_expr %prec SIMILAR"
the action is as follows
{
FuncCall *n = makeNode(FuncCall);
n->funcname = SystemFuncName("similar_escape");
n->args = list_make2($5, makeNullAConst(-1));
n->agg_star = FALSE;
n->agg_distinct = FALSE;
n->func_variadic = FALSE;
n->over = NULL;
n->location = @5;
$$ = (Node *) makeSimpleA_Expr(AEXPR_OP, "!~", $1, (Node
*) n, @2);
}

I think the n->location should be @3.

Thanks,
Gokul.
