+### Allow explicit append with `dbRecordsOnceOnly!=0`

+Previously setting `dbRecordsOnceOnly!=0` prevented any further changes to a record via a .db file.  eg.

+`dbRecordsOnceOnly!=0` previously disallowed appending fields with either form:

+record("*", "myrec") {} # error
+record(ai, "myrec") {}  # error

+
+Beginning with this release, `dbRecordsOnceOnly!=0` allows appending when explicitly intended (when record type is `"*"`).

+record("*", "myrec") {} # allowed
+record(ai, "myrec") {}  # error
