was done so that contents of spanning cells would not be visible when editing
  began.  Rather than doing that I've adjusted the grid to pretend the cell
  being edited is empty.

- Some cleanup editing and assigning text into cells.  Still can not directly
  call redo from the cmd.  Something screws up the memory associated with the
  text entry widget ??

	* src/commands.c (cmd_set_text_undo) : Special case VALUE_EMPTY.
	  Move to the previous cell only after reverting its value so that the
	  edit area is updated.
	(cmd_set_text) : Retrieve the old text of the cell directly.

	* src/sheet.c (sheet_set_current_value) : Delete and merge into...
	(sheet_accept_pending_input) : Here.  Harmonize the logic with.
	(sheet_cancel_pending_input) : this function.
	(sheet_set_text) : Publicize.
	(sheet_stop_editing) : Removed storage of value of cell being edited.
	(sheet_start_editing_at_cursor) : Ditto.

	* src/workbook.c (accept_input) : Use sheet_accept_pending_input.
	(redo_cmd, undo_cmd) : cancel pending input.

	* src/item-grid.c (item_grid_draw) : Pretend that the cell being
	  edited (and anything it spans) are empty.

	* src/sheet.c (sheet_duplicate_colrow) : Delete unused.
