        * providers/nntp/camel-nntp-stream.c:
        * providers/nntp/camel-nntp-store.c:
        * providers/nntp/camel-nntp-summary.c: Make debug run based on
        'nntp' debug option.

        * providers/nntp/camel-nntp-stream.c (stream_fill): if we get a 0
        read, return ECONNRESET.  This should really have been put on the
        stream for that imap hack fix.

        * providers/nntp/camel-nntp-store.c (camel_nntp_try_authenticate):
        retry if the password attempt failed.

        ** See bug #68556.

        * providers/nntp/camel-nntp-store.c (xover_setup): don't overwrite
        exception if we get a failure.
        (camel_nntp_command): if we continue, then set the return code to
        -1, so we re-loop rather than abort.
