Space-separated issues when handling CSVs with Pandas

According to the Pandas I/O API documentation,

read_csv(filename, sep='\s+')

or

read_csv(filename,delim_whitespace=True)

It would be good if

The following options are also useful:

• header=None—No header line.
• skipinitialspace=True—Ignore the leading blank characters.

The following is an example of execution.For clarity, I create buffers from strings instead of reading from files.

>>import StringIO
>>import pandas as pd
>>buffer=StringIO.StringIO(""000000"   
... 0  12  12  12
... 0 123 123 123
... """)
>>>data=pd.read_csv (buffer,header=None,delim_whitespace=True)
>> data
   0    1    2    3
0  0    0    0    0
1  0   12   12   12
2  0  123  123  123
