tests: stabilize change for handling not quoting non-empty-directory The change originated in cb1329738d64. I suspect the problem is with the combination of (re) and the '\' to '/' retry on Windows. I've no idea if py3 on Windows needs the quoting, since it can't even run `hg` with no arguments. (It's dying somewhere on the ctype declarations when win32.py is imported.)
