parse.y: Fix locations of NODE_NIL in endless ranges.

* parse.y: Fix to start with the end of dots.

  e.g. The locations of the NODE_NIL is fixed:

  ```
  1..
  ```

  * Before

  ```
  NODE_NIL (line: 1, location: (1,0)-(1,3))
  ```

  * After

  ```
  NODE_NIL (line: 1, location: (1,3)-(1,3))
  ```
