line_width failure
Two examples where line_width display option requirement is not met:

``` python
In [1]: import pandas as pd

In [2]: pd.__version__
Out[2]: '0.11.0.dev-250c8e0'

In [3]: len(repr(pd.DataFrame(123456, range(5), range(15))).split('\n')[1])
Out[3]: 92

In [4]: pd.options.display.max_columns = 100

In [5]: len(repr(pd.DataFrame(0, range(5), range(35))).split('\n')[1])
Out[5]: 104
```
