Is it just the "+/" tests, or are there other failures?  My notes say I
got a clean run with the old mh-unit tests on Mailutils 3.5, except for
the "+/tmp" tests.  Based on my notes, I also had a copy of Mailutils
3.10, which I played with briefly and expected to pass the tests, but it
looks like I never actually ran the test suite on Mailutils 3.10.

In any case, it looks like we should mark the tests that fail with
Mailutils as expected to fail for that variant, and circle back later to
address them.
