As it turns out, groff 1.00 does the same thing.  Why is the order of testing
important?

BTW, just in case it needs to be said exactly what I want to happen, what I am
after is that the code after the if statement will only be executed IF the
I number register is equal to a 0 AND the G number register is equal to a 1.
