The following issues were fixed: * comparison too broad (e.g. "0" misinterpreted as "true") * python: comparing string with number (is never equal in python) * unwanted non-zero exitcode (compound command "&&" as last command in shell code block (e.g. "case" or "if" branch)) * access to unset variable (shell style issue)
