The old test was just bad, wasn't it?
Meaning that the 2 settings were fetched serially before, and in a single command now. The code change must've been done without correcting the tests at some point prior, mustn't it?

I wonder if stderr=-2 is actually significant, but then while the value could be checked against ANY, the presence of the kwarg cannot be easily ignored, which is a bit of an impasse.

Happy to have this change regardless :)
