title: Untracked files lost after git stash, working on branch and stash pop
body: <p>Please understand the scenario:<br>
  1. created a new branch a day ago and pushed my work there.<br>
  2. worked on sublime whole day, modified existing files, created some new files.<br>
  3. Didn't add or commit, but stashed, switched to another branch, commited there and popped the stash<br><br>
  Whoa !! new files (untracked files) lost</p>
  
  <p>Is this the normal behaviour of stash or I might get this data back.</p>
  
  <p>Any help would be appreciated.
  Thanks :)</p>
