i don't believe this is a change; that's how it should always work. execve() returns ENOEXEC if the file doesn't have the right magic header. sh will attempt to interpret the file as a script after that error, but i don't think doas should have such a fallback. it may not be a sh script, and then weird and possibly bad things will happen (has happened before).
