	tag operations too (but don't count them when deciding whether to
	combine at all.)

	consistency.
	(delete_operation): New function.
	(insert_text): Remove all tags from the newly inserted text to
	prevent tag inheriting from accidentally spoiling undo/redo
	consistency.
	(apply_tag, remove_tag): New functions.

	* (Globally in board/: add BoardStackEntry structure that
	encapsulates `move_number' and, possibly, `grid_copy' fields.
	Include it in all game-specific stack entry structures.)

	field.
	(sgf_node_duplicate): Copy `to_play_color' field.

	board_position_list_delete() uses assert().

	* (Globally in gui-gtk/: use GLib g_return_*(), and other debug
	macros instead of plain assert().  The intention is to make Quarry
	more robust against programming errors.)

	`last_assigned_state_index' and `unmodified_state_index'.
	(quarry_text_buffer_delete_range): Adjust renamed `state_index' so
	that it counts different buffer states, not just the number of
	modifications (these are different after undo operations.)
	(quarry_text_buffer_insert_text): Likewise.
	(quarry_text_buffer_modified_changed): New function
	(quarry_text_buffer_undo): Set the buffer to unmodified state if

	cannot happen here.
