2004-06-08  Jeffrey Stedfast  <fejj@novell.com>

	* em-folder-tree.c (emft_tree_row_collapsed): Only change the
	cursor if the currently selected folder is a subfolder of the
	folder collapsed. Fixes bug #59801 without breaking bug #57665.
	(emft_tree_test_collapse_row): Renamed from
	emft_tree_collapse_row() to match the new signal we are connected
	to.
