bug in string.join()?

Coffee went everywhere when I read that

It threw me somewhat at first:

>>> import string
>>> list = ["i've","come","for","an","argument"]
>>> print string.join(list)
i've come for an argument
>>> print string.join(list," ")
i've come for an argument
>>> print string.join(list,"")
i'vecomeforanargument
>>>                                      

so the " " is implicit. i've sometimes thought it would be more intuitive to 
have the "" behaviour as the implicit behaviour, but it's simple enough either 
way i guess.
