Many tests use `program ... && fail=1` to ensure expected error situations are indicated. However that would mask an unexpected exit (like a crash). Therefore explicitly check the expected exit code. Note where error messages are also verified, the extra protection is not added. * tests/init.sh (returns_): A new helper function to check the return code of a command, and used throughout the tests. * cfg.mk (sc_prohibit_and_fail_1): Add a syntax check to avoid new instances of this issue.
