I had read that, and it was discussed so many times that I do not
see a sense of doing that again. Someone should just prohibit one
of the ways, and standardize the other. Until it is done, any reviewer
can stick to his own favorite way, and mine is to do not clog test
directories with hundreds and thousands of files.

It is changed, but in fact it is still the same. When you have one file,
you can reuse some of existing places to make new tests shorter and
simpler. Strictly speaking for such a bug I wouldn't add a test at all.
It is rather an old typo than a real bug which could return in future.

My diff is below. The same diff is in a separate commit on top of your
branch.
