The unwanted changes are displayed in the review window", so aside from nowikis, we need to find out why it deletes some bits of the text.
Also adding http://fr.wikipedia.org/w/index.php?title=Romain_Alessandrini&diff=95638901&oldid=95638848 which as the previous one happened after a template was left open. I think this should happen to prevent | signs to be shown as they are usually markup and not really wanted in an article, but I still can see them in View mode, so I need to understand more about this behavior. Thanks.
