I never knew that a shell script could work without a shebang line.
That was the simplicity of the original system, where you just made the
file executable. The shell would fork and exec as usual. When the exec
failed, the shell noticed that errno was ENOEXEC (not a runnable file)
and started interpreting the script itself.
