jochen 9aeb5f4493 Keep a restricted message past its stream's age as a record without its body, as ADR 0376 §3 says (issue 728)
Reverts 45b6c347, which kept nothing of such a message and raised an aged-out
condition: that departed from an accepted decision on a lead's word alone. The
concern behind it (the record keeps the subject, with no age) is its own issue.
