intersection on DatetimeIndex fails for empty indices of "quality"

[Lamarth]

index = pandas.DatetimeIndex(start='2000-01-01', periods=4, freq='T')
index[0:0].intersection(index)

Traceback (most recent call last):
File "", line 1, in
File "C:\dev\Python27\Lib\site-packages\pandas\tseries\index.py", line 845, in intersection
if self[0] <= other[0]:
File "C:\dev\Python27\Lib\site-packages\pandas\tseries\index.py", line 976, in getitem
val = arr_idx[key]
IndexError: index out of bounds

@changhiskhan did a2085e6 fix this?

[changhiskhan]

yeah, I just have it return self/other if self/other is length 0

Thanks for the fixes!
