max_columns=0 no longer switches over to summary view

[lodagro]

In [1]: import pandas as pd

In [2]: import numpy as np

In [3]: pd.set_option('line_width', 250)

In [4]: pd.set_option('max_columns', 0)

In [5]: pd.describe_option('max_columns')
display.max_columns: 
: int
        max_rows and max_columns are used in __repr__() methods to decide if
        to_string() or info() is used to render an object to a string.
        Either one, or both can be set to 0 (experimental). Pandas will figure
        out how big the terminal is and will not display more rows or/and
        columns that can fit on it.


In [6]: pd.util.terminal.get_terminal_size()
Out[6]: (138, 43)

In [7]: df = pd.DataFrame(np.random.randn(2,50))

df wraps it columns, but no switch over to summary view

In [9]: pd.__version__
Out[9]: '0.11.0.dev-dad367e'

Just making sure you're aware of the shiny pd.options shortcut with tab completion.
