--- Comment #3 from Sergio Durigan Junior <sergiodj at redhat dot com> ---
Thanks a lot for the throrough investigation, Andrew!

I can confirm that replacing "di" by "edi" works, i.e., the inferior finishes
(with return code 1).

It's not clear to me whether we should special-case this scenario (doesn't seem
like a very elegant solution); I'll look deeper into this and see if I can come
up with a solution.  Thanks.
