Merge #12887: [trivial] Add newlines to end of log messages.

5b10ab0 [trivial] Add newlines to end of log messages. (John Newbery)

Pull request description:

  Log messages should terminate with a '\n', or the following log will be
  written to the same line without a timestamp. Fix a couple of cases
  where the message is not terminated with a \n.
