[gtk+/multiroot-filechooser: 3/30] Filter and restore the Recently Used list on root URI switching.



commit 5673ef9463bda427a5a2a46aeeff8acb2f373e09
Author: Christian Hammond <chipx86 chipx86 com>
Date:   Mon Feb 1 23:18:18 2010 -0800

    Filter and restore the Recently Used list on root URI switching.
    
    The Recently Used list only shows matches that are within the root URI.
    The entry in the sidebar is available at all times, as recently used items
    can be on remote URIs.
