> LDAPrintTopics uses a PrintWriter to output topics.
> This PrintWriter wraps a File when an output directory is specified and System.out otherwise.
> This PrintWriter is closed and recreated for each topic; which doesn't work for the System.out case (since it closes System.out)
> Fix is to flush the stream and close only in the output directory case.
