Unfortunately, it appears that there isn't one.  I'd thought that, in a
mail exchange on the gtk-devel mailing list, Havoc Pennington had
indicated that setting this should be done in the gtkrc file, but
rereading my saved gtk-devel mail, he spoke of it being a theme option
for the 1.3/2.0 TreeView widget, rather than an option configurable
without changing the theme, and hadn't spoken of it being
gtkrc-configurable or theme-configurable in 1.2 at all.

The expander type is a named property of the GtkCtree object
("GtkCTree::expander_style"), and there's a mechanism in GTK+ for
setting GTK+ object properties by name, but it doesn't appear to be
hooked into the stuff to process gtkrc files; it might be there for the
benefit of Glade.
