Re: [PATCH v4 3/7] remote-mediawiki: show known namespace choices on failure

> If we fail to find a requested namespace, we should tell the user
> which ones we know about, since those were already fetched. This
> allows users to fetch all namespaces by specifying a dummy namespace,
> failing, then copying the list of namespaces in the config.
> 
> Eventually, we should have a flag that allows fetching all namespaces
> automatically.
