Writing RethinkDB Drivers has incorrect AST example for `r.do`

The docs currently show:

[FUNCALL,
  [FUNC,
    [[MAKE_ARRAY, [1, 2]],
      [ADD,
        [[VAR, [1]],
         [VAR, [2]]]]]],
  10,
  20]

// FUNCALL = 64, FUNC = 69, MAKE_ARRAY = 2, ADD = 24, VAR = 10

[64, [69, [[2, [1, 2]], [24, [[10, [1]], [10, [2]]]]]], 10, 20]

I believe it is incorrect and should instead read:

[FUNCALL,
  [[FUNC,
    [[MAKE_ARRAY, [1, 2]],
      [ADD,
        [[VAR, [1]],
         [VAR, [2]]]]]],
  10,
  20]
]

// FUNCALL = 64, FUNC = 69, MAKE_ARRAY = 2, ADD = 24, VAR = 10

[64, [[69, [[2, [1, 2]], [24, [[10, [1]], [10, [2]]]]]], 10, 20]]

There is a missing [ before FUNC and at the end there is a missing ]. I think it may be valid REQL to have both of these brackets emitted but it's confusing when the node.js driver does emit these.
