Modified patch from muppet <scott@asofyet.org> to keep child directories

Thu Mar  4 01:32:19 2004  Jonathan Blandford  <jrb@gnome.org>

        * gtk/gtkpathbar.c (gtk_path_bar_set_path): Modified patch from
        muppet <scott@asofyet.org> to keep child directories around if we
        change to a child.

        * gtk/gtkpathbar.c (_gtk_path_bar_set_home_icon): Start of
        icon-setting functions.  Not used yet.
        (_gtk_path_bar_set_root_icon): Ditto.
