Fair point, I'll reroll the series and change skipped tests to yellow
(non-bold, to distinguish from known breakages which are bold yellow).

Correct.

They are right (at least as I intended), but I agree it's a bit
confusing.

It's actually one test which is both fixed *and* in some sense broken.
The confusion arises from the ambiguity of the word "broken", which
could mean either "failed as expected" or "expected to fail but
didn't".  Previously it was just the former, but my patch changed it
to encompass both cases.  The motivation behind this was to avoid the

    # passed all $count test(s)

summary message which is overly comforting when one or more tests were
expected to fail but didn't.  However perhaps it's cleaner to keep the
counter buckets separated.  I'll try to come up with a better
solution.
