MultiIndex Column Offset Bug with to_html(index=False)

[woztheproblem]

I'm trying to use to_html() to print a DataFrame that has a MultiIndex column, and I want to hide the index. When I do, the column labels are shifted right by one column. I use:

import pandas as pd
from IPython.display import HTML
df = pd.DataFrame({'a': range(10), 'b': range(10,20), 'c': range(10,20), 'd': range(10,20)})
df.columns = pd.MultiIndex.from_product([['a', 'b'], ['c', 'd']])
HTML(df.to_html(index=False))

and the result is:

Seems to me to_html() isn't properly accounting for the index=False when there is a column Multindex. With single-level column index ( df.columns=list('abcd') ) it prints fine. With index=True, to_html() also works fine.
