Use “/give@s（No Spaces）”can get items with commands in is not enabled

When you cheat in is not enabled input "/give@ s" (no Spaces), you can get items with commands. I even won the achievement in this way.（Please cancel my——WhoksBC‘s achievement called “diamond！” if possible）
So many people know this bug now，please attach importance to it!
