DKIM downgrade example again; this time debugged

As well as previous commit's `len_3` -> `length_3`, we were missing
braces around the expansion operator, resulting in trying to dereference
an unknown variable `$length_3`, and we were missing the outer braces
from the `or` expansion condition.

We really need a better way to test ACL expansion without a full harness. :(

This bug-fixed version is now running on my system.
