Hmph.

This does not catch if the outer expect_success does not catch a
failure in the inner expect_success and signal a failure.

When I asked if this kind of breakage is an easy mistake to catch by
the test lint, I had something along this in mind:

	test_expect_success () {
		if test -n "$GIT_IN_TEST_EXPECT"
		then
			BUG caling "$GIT_IN_TEST_EXPECT" inside test_expect_success
		fi
		GIT_IN_TEST_EXPECT=test_expect_success

		... do the 'eval the given test body' thing ..

		GIT_IN_TEST_EXPECT=
	}

After all, the error is in the outer expect_success in that it
called another one, so it feels more natural that the called inner
expect_success to notice the situation and barf.

Thanks.
