Title: Robust paths

one commit just adds unit test, the other fixes a vulnerability when env var has trailing slashes (maybe an unlikely case)
The code comparing path + subfolder has become quite ugly, and I would prefer an implementation based on os.path functions rather than string comparison, can implement that if you want me to.
