Reindex versus ix gotchas documentation text does not match example code
In the gotchas documentation, in the section "Reindex versus ix gotchas", there is the following example:

```python
In [28]: s = pd.Series([1, 2, 3], index=['a', 0, 1])

In [29]: s
Out[29]: 
a    1
0    2
1    3
dtype: int64

In [30]: s.ix[[0, 1]]
Out[30]: 
0    2
1    3
dtype: int64

In [31]: s.reindex([0, 1])
Out[31]: 
0    2
1    3
dtype: int64
```

The example shows both `ix` and `reindex` behaving the same. The subsequent text, however, states that they are expected to give different results:

> Because the index in this case does not contain solely integers, `ix` falls back on integer indexing. By contrast, `reindex` only looks for the values passed in the index, thus finding the integers `0` and `1`.

I am not sure if the indexing behaviour is correct and the documentation is wrong, or vice versa. It appears that in this case `ix` does not fall back on integer indexing while the text states that it does.
