I thought about this. We have never needed PQsetdbLogin() to handle
zero-length strings specially in all the years we used it, so I am not
sure why we would ever need PQconnectdbParams() to handle it. I am
thinking we should make PQconnectdbParams() handle zero-length strings
the same as NULL, and document it.
