        Does the above mean that nntp-open-server is only used by
        ‘url-news’ (and thus could be removed once it’s gone), /or/ does
        that mean that ‘url-news’ fails to call ‘nntp-open-server’
        properly (in which case, what’s the correct way to call it)?

        (My understanding of the nntp-open-server code is that it /does/
        indeed have a bug, which is somehow /not/ triggered by Gnus, but
        /may/ very well be triggered by just whatever other code that’d
        happen to call it.)

        Incidentally, there’s a reason for me to support the removal of
        url-news.el from Emacs proper, as (I guess) it would make it a
        bit easier for me to offer it as a separate package.
