Update pan to 0.11.4, the last GNOME version of pan.  Changes include tons
of bugfixes, plus

    NEW FEATURES
        * Added the ability to specify which characters are recognized
          as quote prefix characters, so nonconformists not using '>' to
          quote text will still have their articles colored right in Pan.

        * Added "Go to previous article" navigation button.

        * Added support for decoding yenc-encoded attachments!

    UPDATES
        * Add a new preference option, dictating whether failed tasks
          should be removed from the Task Manager. Unconditionally clearing
          the queue didn't go down too well with some of the leechers.

        * Added support for mime articles which explicitly specify a
          Content-Transfer-Encoding of x-uuencode.

        * Make sure that the default window size is large enough that a
          full line, up to the default number of wrap characters and with
          the default font, will fit without scrolling.

        * The 'Download Articles' dialog now switches the articlelist to
          the group when the headers have been downloaded.
          Since this dialog is mostly used to sample a (potentially large)
          group, this seems the more intuitive approach.

        * Added Message-ID to Find Article's search criteria.

        * If an article no longer exists on the news server, tasks to read
          that article are now automatically removed from the Task Manager.
