Then every test that had this issue would have to be modified to add the option. I think it would have to be an environment variable that suppresses the other environment variables: `FILECHECK_IGNORE_ENV=1` or something. Then test suites could add that in their config files, and tests would be written as normal.
Luckily, so far we don't seem to need that level of confusion.
