[Curtis Gedak <gedakc src gnome org>]

commit 59f684d8cdc5ea77f63e44ff8c92977647da2df5

    Always show the File System Support dialog legend (#342682)
    
    Make the legend always shown, ready for when the dialog is resizable.
    
    Change the widget containing the legend from an expander to a frame
    widget.  Set the frame to be borderless using a bold label as
    recommended in the GNOME Human Interface Guidelines 2.2.1 / Controls /
    Frames and Separators.
