The current version of the standard is the result of it relaxing the previous edition's requirements. I don't know if the test suite still tests for behavior with \r\b\f\v in $IFS.
Which (of any) character other than space, tab, and newline (which are in the locale's space class) count as IFS whitespace is up to the implementation.
Now. Not during the period we're talking about. And the reason it got
relaxed is because there were implementations that didn't conform to the
previous edition's text.
