I think you missed the subsequent discussion about the fact that it
was defaulting to zero, and the original author's intention to change
it to default to 1, since he though that what had been committed would
default to 1 automatically.

If your response is intended to indicate that this *won't* be defaulted
to 1, then I am very, very happy.
