This is now *thoroughly* fixed in CURRENT, as I finally got around to
ripping out all of that code and replacing it with something that deals
with the corner cases.

I'm not sure it's worth trying to do more with this in STABLE; the code is
fundamentally wrong in the way that it handles data from the helper
program, and I'm worried that if I rework it wrong, I'll cause infinite
loops instead of just bad error messages.  The right thing to do is
probably to backport the change from CURRENT, although that would be a
fair bit of work.
