Sorry, I thought it made sense in context of what I am doing in the
following patch. All I am trying to do is to provide an effective way
of grouping test cases. To be clear, the idea, assuming you agree, is
that we would follow up with several other patches like this one and
the subsequent patch, one which would pull out a couple test
functions, as I have done here, and another that splits those
functions up into a bunch of proper test cases.

I thought that having that many unrelated test cases in a single file
would just be a pain to sort through deal with, review, whatever.

This is not something I feel particularly strongly about, it is just
pretty atypical from my experience to have so many unrelated test
cases in a single file.

Maybe you would prefer that I break up the test cases first, and then
we split up the file as appropriate?

I just assumed that we would agree it would be way too much stuff for
a single file, so I went ahead and broke it up first, because I
thought it would make it easier to review in that order rather than
the other way around.

Cheers
