Yes, that is exactly what made me question the code.  With the
current code, valueless true cannot be updated with "--value"
restriction, ever, because it will never match anything.

In any case, the patch is a strict improvement over the current code
that segfaults.  Making it aware of "--type=bool" and have it treat
synonymous values of true/false properly would be better left as a
follow-up topic.

Thanks.
