Merging changes:

2001-12-04  Christopher James Lahey  <clahey@ximian.com>

	* configure.in (GAL_CURRENT): Bumped version number to 0.18.99.0
	and CURRENT to 19.

2001-11-21  Christopher James Lahey  <clahey@ximian.com>

	* gal/widgets/e-reflow.c, gal/widgets/e-reflow.h: Handle
	selection_row_changed signal.

	* gal/widgets/e-selection-model-array.c,
	gal/widgets/e-selection-model-array.h: Properly send
	selection_row_changed signals if changing from a single row
	selected to a single other row selected or if moving the
	selection_end by a single row.

	* gal/widgets/e-selection-model.c,
	gal/widgets/e-selection-model.h: Added selection_row_changed
	signal.
	(e_selection_model_select_as_key_press): Fixed the case statement
	here to make MULTIPLE and EXTENDED the same as BROWSE instead of
	as SINGLE.

From gal/e-table/ChangeLog:

2001-11-21  Christopher James Lahey  <clahey@ximian.com>

	* e-table-item.c, e-table-item.h: Handle selection_row_changed
	signal.  Keep track of the old cursor row so that we only redraw
	two rows when the cursor changes.

	* e-table.c, e-tree.c: Handle selection_row_changed signal.

	* e-tree-selection-model.c: Properly send selection_row_changed
	signals if changing from a single row selected to a single other
	row selected or if moving the selection_end by a single row.
