* new version 2.20.4

   * If the charset of a message can not be determined, use the value set
     in the "Unknown Character Set" option.

   * Resizing setup screen will redraw screen.

   * Unix Alpine only. Experimental: If Alpine/Pico finds a UCS4 code
     in the width ambiguous zone, it will use other means to determine
     the width, such as call wcwidth.
