Good catch. Maybe coverity would have found that in a second pass? Or I
was just too blind... As I said, this round of work on coverity was
disrupted by coverity's server downtime, which is still not fixed.

Anyway, this isn't wrong, only incomplete. I'd rather not resend the
whole series because of this. When coverity is up again, I'll do
another round of fixes.
