	* src/dialogs/dialog-autocorrect.c (autocorrect_tool) : Suppress
	  warnings.

	* src/commands.h : Do not declare autocorrect_tool here.

	* src/item-grid.c (item_grid_draw) : Add support for hiding the
	  grid_lines.
	* src/sheet.c (sheet_new) : Init show_grid.

	* src/functions/fn-math.c (gnumeric_sumif) : Do not ignore empty cells
	  if there is a result range that we need to stay in sync with.  Fix
	  handling of inter-sheet references.
