        Patch for 161909:

        * src/sheet.c (sheet_cell_remove): Add new arg to control whether
        to flag dependencies.  All callers changed.
        (cb_empty_cell): Take whole flags argument.

        * src/clipboard.c (clipboard_paste_region): Handle new flag
        PASTE_NO_RECALC to help sorting speed.

        * src/sort.c (sort_contents): Paste using PASTE_NO_RECALC and
        handle dependencies ourselves.  Don't qsort if we have less than
        two elements.
