	on the clipboard marked for cutting or for copying?

	* src/selection.[ch] (sheet_selection_ant): Deprecated, remove.
	(sheet_selection_unant): Idem.

	* src/sheet-control-gui.[ch] (scg_selection_ant): Rename
	to scg_ant and add a ranges parameter where the ranges to

	* src/commands.c (cmd_ins_del_colrow_undo): Remove ugly ant-hack,

	(cmd_ins_del_colrow_redo): Idem
	(cmd_ins_del_colrow): Oh dear, we were actually storing both
	the cut and copied area as a cut area and we were actually
	cutting even if the range was a copied area after shifting.
