The tree used to prelight both nodes and expanders.  I was told that
prelighting nodes was confusing, and when I turned it off I apparently
turned off prelighting expanders as well.  Turning it back on should be
straightforward.

If the lines are important, I suppose we could add a call like
gtk_tree_view_set_lines_expander_hint to go along with the rules_hint
function.  Currently there's not a lot of code to draw it (and I'm not
100% sure how I'd do it themed) but it would not be too hard to add.

Assuming that it's not too dependent on much, it would be good to port
the component to GtkTreeView (not as a component, mind you, but just in
a top level window.)  This would give us a good idea if GtkTreeView will
be good enough, and let us know what needs to be added to it.

Help us make the stock stuff good enough!
