Actually, the approach of reversing the logic of the -a option doesn't
keep the consistence of literal input parameter __bool__ __all__ of the

By the way ,I had sent a patch to fix this two month ago but Keith missed it.
A new updated patch of this was sent a minute ago. Hope Keith would catch it.
