Excellent as the changes appear to address incorrect number of delimiters.

I think that the default invalid_raise should be True.

One 'feature' is that there is no way to indicate multiple delimiters 
when the delimiter is whitespace.
1 2 3 4
1     4 5

Which I consider a user beware issue when using whitespace as the 
delimiter especially in Python.
