title: What is Git pruning?
body: <p>I've accidentally pruned some remote branches and I don't really know what the consequence of this is (I clicked the "Prune remote branches" button in Git Extensions, thinking it would delete a remote branch).</p>
  
  <p>The official documentation says "git-prune - Prune all unreachable objects from the object database ". I don't really understand what this means. I'm guessing this might have removed merged branches but I'm not really sure.</p>
