I see. I'm still not sure the expected convenience factor (avoiding some
grep-like post processing? but couldn't you compare the combined output
just the same?) outweighs the weirdness / least surprise factor (having
two variations of the same diagnostic message split on two separate
output streams).

Yes, if the split has to stay, I don't have a better suggestion.

Thanks,
