  This one worries me a bit because environment variable values can contain non-ASCII. However, the changed code only operates on `HG_` variables and I //think// those variables are well-sanitized and should be ASCII safe.
  
  Also, `os.environ` is `str`/`bytes` on Python 2 and the `.encode()` is nonsensical. But Python 2 doesn't care, so meh.
  
  Since this is testing code, the barrier for change is low. And the failure mode is pretty obvious. So I'm OK landing this now and fixing later if it causes problems.
