Summary: Problem in join function definition

Initial Comment:
There is a problem in the last sentence of the join 
definition. 

==========================================
join( words[, sep]) 

Concatenate a list or tuple of words with intervening 
occurrences of sep. The default value for sep is a single 
space character. It is always true that "string.join
(string.split(s, sep), sep)" equals s. 
==========================================

It is true that string.join(string.split(s, sep), sep)" is 
always equals to s. 

But string.join(string.split(s)) is not always equals to s 
especially for repeated sequence of spaces.

And?  If the documentation explains how something works, 
does it also have to list a couple of other things that doesn't 
work?
