OK, I will make that cosmetic change.

YES! Well, sort of. I didn't have any other operators but while I thought
that both were the same (after all, I contributed it) someone must have fixed
the one in CVS before adding it. The one I was working with had the
operators working with chkpass on both sides. As soon as I fixed that it
worked again.

In 7.2 the cstring and chkpass types fail in the function definitions because
they have not been defined so I had to stay with opaque. In fact, how will
that work in 7.3 anyway? We declare the functions to take or return a
chkpass before we define it.
