>Summary: "string".split behaviour for empty strings

Initial Comment:


"".split() -> []



"".split(' ') -> ['']



It is not clear from the documentation as to what is

the defined behaviour in the above case. To say the

least, it is 

completely counter-intuitive..(splitting an empty

string should

return the list [''] in both cases).



>From stringobject.c, the behaviour of split_whitespace

(i.e split called without sep) and string_split (split

called with sep) is different for empty

strings..perhaps the function split_whitespace needs to

be patched.
