	Fixed bug where a renamed node in the tree view doesn't get
	resorted:

	* libnautilus-extensions/nautilus-ctree.c (set_node_info): if
	the ctree is in auto-sort mode, sort the branch containing the
	changed node


	Fixed a crash in the tree view when expanding nodes that have
	been moved across directories:

	* components/tree/nautilus-tree-node.c
	(nautilus_tree_node_remove_children): new function, unparents
	all children of the given node

	(nautilus_tree_node_destroy): emit a warning if the list of
	children is non-null (then call remove_children). Ideally the
	remove_children function should get called before the final
	unref of a directory node

	* components/tree/nautilus-tree-model.c
	(report_node_removed_internal): call
	nautilus_tree_node_remove_children before unref'ing the node


	Mostly fixed bug where expansion state hash table accumulates
	cruft over time (e.g. directories that no longer exist or got
	moved to locations where they can never be displayed):

	* components/tree/nautilus-tree-view.h
	(NautilusTreeViewDetails): added `view_node_to_uri_map' hash
	table. This is used to map view nodes to the URIs we believe
	they are displaying. This is necessary since by the time we
	find out about changes to nodes, the names of the underlying
	NautilusFile objects have often already been changed

	* components/tree/nautilus-tree-view.c
	(unlink_view_node_from_uri, link_view_node_with_uri,
	map_view_node_to_uri): functions accessing the new hash table

	(nautilus_tree_view_would_include_file): new function, returns
	true iff the given file may possibly appear in the tree view.
	Climbs through all parents of the file to do this

	(nautilus_tree_view_model_node_renamed_callback): only
	propagates the expansion state if the would_include function
	indicates that the new URI of the file would be included in the
	tree view

	* components/tree/nautilus-tree-model.c (report_node_changed):
	no need to suppress the `node_removed' signal when renaming the
	node (now that the view always deletes the expansion state of
	the correct URI)

	* libnautilus-extensions/nautilus-file.c,
	libnautilus-extensions/nautilus-file-private.h,
	libnautilus-extensions/nautilus-file-utilities.c,
	libnautilus-extensions/nautilus-file-utilities.h
	(nautilus_file_name_matches_hidden_pattern,
	nautilus_file_name_matches_backup_pattern): moved these
	functions from being private in nautilus-file to being public
	in nautilus-file-utilities


	Fixed tree view bug where moving nodes across directories still
	loses the expansion state:

	* components/tree/nautilus-tree-model.c
	(nautilus_tree_model_directory_files_changed_callback):
	separated the cases of the file being deleted and it being
	moved across directories. In the move case emit the
	`being_renamed' signal so the expansion state gets propagated

	(nautilus_tree_view_remove_model_node, forget_view_node): moved
	the code to delete the expansion state from forget_view_node to
	nautilus_tree_view_remove_model_node - avoids deleting
	expansion state of nodes that will later be renamed. It may
	leave non-existent directories in the expansion state, but this
	is a lesser bug than losing the expansion state totally. Also,
	use the map_view_node_to_uri function to find the URI whose
	expansion state needs to be removed


	Fixed the bug where tree view icons often got chopped at top
	and bottom when they're drawn (if the icon height is greater
	than the font height). This means that fewer rows may fit in
	the same vertical space, but visually it's (imho) a huge
	improvement (I think this is bug 6085):

	* components/tree/nautilus-tree-view.c
	(nautilus_tree_view_initialize): call gtk_clist_set_row_height
	with the maximum of the font height and the icon height

	* libnautilus-extensions/nautilus-ctree.c (draw_row): always
	calculate row_center_offset locally, and do it in such a way
	that the text really is in the center of the row!


	Fixed bug 5165 - repeatedly expanding and collapsing an empty
	directory doesn't change how the node's icon is drawn after the
	first expansion:

	* libnautilus-extensions/nautilus-ctree.c (real_tree_expand,
	real_tree_collapse): before returning, call tree_draw_node on
	the node that changed state
