The latter. I included a note in my reply that those two tests were included
solely to illustrate the behavior was as expected and would not be included in
the actual patch revision.

I generally agree. I was mostly just trying to address the spirit of the
suggested changes.

As I mentioned at the end of my most recent reply to Junio [1], I'm OK with
either the diff I proposed [2] (minus the extra tests) or just reverting the
changes entirely and going with what we did in the v5 patch.

At the end of the day this seems like it was a minor nit on some test code that
ended up leading down a rabbit hole due to the multiple layers of nesting. I
only proposed the diff [2] because it seemed to fully address to original
concern without doing anything particularly egregious (unlike v6 w/ the helper).

So while I prefer my diff, I'm not at all attached to either solution and will
implement whatever you and Junio decide for v7 with no complaints.
