[Docu] option "nn" requires two minus signs to work

Short form of --numNews (--nn) has two characters and hence requires two minus signs to work.

Hmm the idea of these short forms is that you don't have to type two --. We should probably choose another short form than nn.

Ok that would be ok for me too. But currently the docu is wrong 😊 and I need some retries from time to time as -nn does not work without any visible error. Feel free to change the option if you prefer. Martin
