This type of modification should be done at the theme level.  With the
CList, we had each app author pick the mode that they liked most, rather
then have any consistent Look and Feel.  Currently themes can draw their
own expanders.  There isn't support to draw the lines currently, but
it's not hard to add to someone sufficiently

I don't feel it's too strange, and it is very similar to the Macintosh
tree.  As I said, if someone wants to do the leg-work to make the tree
work with a windows-style tree, that's fine too.
