Update to 2.2.11
    
    - New upstream release 2.2.11
      - This is a minor maintenance release and minor feature release; the only
        exception to that is the Python 3 compatibility, which is a major change
        and may introduce new bugs
      - Double click selection has been improved (for example selecting a function
        name that has underscores), and is now configurable per language
      - Bluefish now has a feature to fill a line with spaces up to a mouse click,
        so you can start typing in any position on the screen (with a fixed width
        font)
      - A crash when running very large replace actions on disk on many files has
        been fixed
      - Search and replace now ignores backup files by default
      - Cursor highlighting and line highlighting have been fixed for a rare bug
      - A small new feature has been added, to insert output from an external
        command in the current cursor position
      - Many language files have seen updates, most notably CSS, Python and HTML
      - A data loss bug - when an unknown encoding was selected - was fixed; the
        fallback is now to save as UTF-8
      - A bug when saving with unknown characters in the filename has also been
        fixed
      - Printing has been improved, such as printing in landscape
      - Some small tweaks to the UI have been implemented, e.g. can now search in
        files in the filebrowser (right click a directory)
      - Search results can now be shown in the output pane
      - The current identifier can be selected using <shift><control><i>
      - Various fixes when Bluefish is run on top of Wayland
