Subject: [PATCH] Fix locations of NODE_UNDEF in undef with multiple args

* parse.y: Fix the beginning position of trailing NODE_UNDEF.

  e.g. The location of the NODE_UNDEF for `b` is fixed:

  ```
  undef a, b
  ```

  * Before

  ```
  NODE_UNDEF (line: 1, location: (1,6)-(1,10))
  ```

  * After

  ```
  NODE_UNDEF (line: 1, location: (1,9)-(1,10))
  ```
