Dear R Developers,
Prediction intervals for weighted regression are treated in
Brown, P. J. (1994) Measurement, Regression and Calibration. Oxford
on p. 35. However, the prediction interval for Z is not really
spelled out in a way that would be accessible for me.
So I give up on this. I find my proposed solution (further updated since
my last mail) plausible, but I don't know and can't find enough theory
to support it.

Ceterum censeo PR#8877 esse corrigendum.
