remove unnecessary settings with NULL_NODE in \X implementation
Remove unnecessary settings of node_array elements to NULL_NODE.
We can do this because we initialize the whole array to NULL_NODEs
and set everything again to NULL_NODEs when creating a sequence or
alternative node.
Also, fix an index error in the initialization of node_array.
