Hi!  Thanks for the review.  I have asked on the gnu-prog-discuss list
what we should do here.  It may take some time to solve this, and I
don't want to hold up the next stable release for it.  So it is no
longer a release blocker.

Now I should really go work on the external signing callback instead,
which actually is the major release blocker right now...
