title: Undo “git add <dir>”?
body: <p>I mistakenly added files using the command "git add dir". I have not yet run "git commit". Is there a way to remove this dir and everything contained within it from the commit?</p>
  
  <p>I have tried <code>git reset dir</code>, but it didn't work. Apparently <code>git reset file</code> is the way to undo it. But I have so many files and so little time.</p>
