I have a feeling that use of test-output-expect-success is trying to be too cute without making the result easier to read, and also makes it harder to debug the test script when it does not work as expected (e.g. you need to see where the output from the actual command is stored by going to the definition of the shell function), and would have preferred to see these three tests written without it (and instead using explicit 'expect' vs 'actual' comparison), but at least the patch below shows what I meant when I suggested updating the tests to reuse the existing history (I do not speak for Johannes, but I am guessing we are on the same page on this one).
