Yea I didn't like the original naming here either, any suggestions? I avoid `path` in these because of the existing `pathsep`, maybe `fsroot` and `fssep`?

What are you suggesting in place of hardcoding `C:\`? I don't think we could detect what folks are using in the tests, so it does seem like it would be up for individual tests to do this however it makes sense. It appears that there are a few hundred uses of this in tests today, does that break in general if you're using another drive?
