示例1: shiftIndentCount

	public static shiftIndentCount(line:string, column:number, tabSize:number): number {
		// Determine the visible column where the content starts
		var contentStartVisibleColumn = CursorMoveHelper.visibleColumnFromColumn2(line, column, tabSize);

		var desiredTabStop = CursorMoveHelper.nextTabColumn(contentStartVisibleColumn, tabSize);

		// The `desiredTabStop` is a multiple of `tabSize` => determine the number of indents
		return desiredTabStop / tabSize;
	}
