Pondering more, did you mean:

  test_expect_success '--porcelain=bogus complains about format' '
	echo bongo bongo bongo >>file &&
	test_must_fail git commit -m next -a --porcelain=bogus
  '

?

expect_failure is for tests which we _want_ to succeed, but do not yet
(so they get annotated in test results appropriately). expect_success is
for an outcome we expect to happen, but which may involve specific steps
returning failure.

The names are kind of confusing in that regard.

I wonder if just "test_expect" would be a better name for
test_expect_success, and an argument or environment variable to trigger
"we know this is currently broken" rather than having a separate
test_expect_failure function. That's clearly outside the scope of your
series, of course.
