I'm dubious about this.

stream-record does not have an NL terminator and needs one, yes.

But async-record already gets an NL terminator in the grammar
and does not need a second one.

  async-record -> exec-async-output | status-async-output | notify-async-output
  exec-async-output -> [token] "*" async-output
  async-output -> async-class ("," result)* nl

For example, gdb.mi/gdb669.exp gives:

  # gdb.log excerpt
