That's why the word "always" is there. :)

My point was that your line of logic was not as clear-cut as you suggested.  One could argue that dropping whitespace to become the empty string is more reasonable than dropping it become "no string".

Is it your opinion that no changes to textwrap should be made in any versions that change existing behavior on some input?  Otherwise, what are your criteria?
