Done.

That blurb is added at runtime by `advise_if_enabled()`. I originally added it
but it was giving me the line twice so I took it out.

Ah. The "${@:2}" is a bashism I think. I got it from [1] to try and grab all the
remaining arguments. Changed to just shifting.

The &&ing together was a mistake on my part (not paying attention and mimicking
the &&ing present in the test cases). I've removed that.

Done.

The following are what I have made for this set of changes (against v4).

Also, Is there an easier way to debug the `test_expect_success` statements? I
tried enabling tracing mode but it doesn't seem to trace into those statements.
