pydata/pandas — pull request #5298 by jreback (2013-10-22 23:40:12+00:00)
Title: BUG: parser can handle a common_format multi-column index (no row index cols), (GH4702)

closes #4702, should help with #5254

Will handle the format generated by ``to_csv`` (which has a an 'extra' line for the index names)
and the more 'common' format

```
In [4]: data = """,a,a,a,b,c,c
...: ,q,r,s,t,u,v
...: one,1,2,3,4,5,6
...: two,7,8,9,10,11,12"""

In [6]: read_csv(StringIO(data),header=[0,1],index_col=0)
Out[6]:
a b c
q r s t u v
one 1 2 3 4 5 6
two 7 8 9 10 11 12
```
