This is an odd way to do this.  If we stop applying your patches at
this step, these tests will still see output from "status --ignored"
that is expected by them, so there is no expect_failure here.

If we decide that the current output from "status --ignored" is
WRONG, and your series to fix "clean -d" FIXES "status --ignored" as
a side effect, then having a step to describe a desired behaviour in
the new world order in the test like this patch does makes sense,
but if that is what is going on, then not just flipping "success" to
"failure", the patch would be changing the expected output as well,
i.e. by adding the ignored files in untracked directories in the
expected output.  Obviously the code at this point after applying
only patches 1 & 2 will not produce such an output, so marking the
test that expects output based on the new world order as "expect
failure" would make sense.  Then your future commit that FIXES
"status --ignored" output would flip _failure to _success.

It is unclear to me if the new behaviour of "status --ignored" is a
bugfix, or a new bug, though.
