Title: except nil in redis status info.

ruby-2.0.0preview1 isn't working ```Hash[[nil, ...]]```. exsample for:

```
test_transformed_replies_inside_multi_exec_block(TestTransactions):
ArgumentError: wrong element type (expected array)
```

Because ruby-2.0.0 validates wrong argument when use Hash[] now. I fixed it.
