title: Reclaim space after aborted git add?
body: <p>I accidentally git added a large (32GB) file to my staging area. After a handful of seconds I noticed (my fans spun up!) and hit CTRL+C. This stopped the process but the ~2GB of space it had used has not been returned to the file system.</p>
  
  <p>How can I reclaim that space? Not that I'm short of a gig or two but having big useless clots of data knocking around somewhere (presumably in my .git folder) bothers me.</p>
  
  <p>I've looked a git clean but that doesn't look like it will help.</p>
  
  <p>The files it has added are...</p>
  
  <pre><code>1.9G    ./objects/pack
  1.9G    ./objects/pack/tmp_pack_lwma1r
  </code></pre>
  
  <p>Can I safely delete these? </p>
