Yuck.  Well, an external influence that can break the automated
build job overnight should be capable of fixing it overnight ;-)

Sounds good.

Thanks for extra careful.

If this is truly urgent, I could merge this to 'maint' and merge the
result upwards to 'pu' and it would hide the issue on my four
integration branches.  But one thing that makes me wonder is if we
can (or want to) do anything to help other people who test build
with pull requests.  I guess they need to rebase on top of whatever
commit that has this fix?  That sounds more like a tail wagging a
dog, though.  I dunno.
