with
> record(ai, "myrec") {}
dbRecordsOnceOnly!=0 currently disallows appending fields with either form:
> record("*", "myrec") {} # error
> record(ai, "myrec") {} # error
Change the meaning such that dbRecordsOnceOnly!=0
allways allows appending when explicitly intended (rtype "*").
> record("*", "myrec") {} # allowed
> record(ai, "myrec") {} # error
Also clearly label this parse error.
