title: Git: Recover the deleted remote branch
body: <p>well, I've made a very terrible mistake which first I just want to delete the remote connection to another repositories.</p>
  
  <p>I've made the command like this: git push dev :test</p>
  
  <p>which after I check on the github, I'm just realize that the branch test already deleted.</p>
  
  <p>Question: how can I get the branch back? Is it possible to undo the command which I've already made?</p>
