This does not work as intended because the exit code of 'break' is always
zero. Unlike 'exit' and 'return', it does *not* pick up the exit code of
the last command that was executed.
That's annoying, but makes some sense because 'break 2' does not mean to
apply exit code 2 to the command, either, but to break out of 2 levels of
loops.
You could put the loops into a function from which you 'return', but that
is obscure in this case. The first iteration was better, IMO.
