 That change is a first step. It helps security by actually escaping the
 data properly, but the extra fields are an issue. I just haven't gotten to
 rewriting it the rest of the way. Patches appreciated. There are dozens of
 places in the ms- files that need to use prepare(), insert(), or update()
 rather than stuffing POST and GET values directly into a query.
