That was the wrong comment (that one applies to rev 1.69, and is arguable
better than the one I used).

1.70 needs:
Don't generate empty trailing arguments when field-splitting
a string that ends with non-whitespace IFS.
    sh -c 'IFS=":"; set -- x$IFS; echo $#' 
now correctly returns 1.

NetBSD's /bin/sh now passes all the IFS tests in:
