title: Mercurial will not recognize new folder in repository
body: <p>I have an existing repo which has been setup correctly and working fine. I deleted an entire project folder from the repo, committed the change, then added another version of the same folder which was not under VC. Now when I try to add or commit files in the new folder, Mercurial does not seem to recognize any of the new files. </p>
  
  <p>Using the TortoiseHg Windows Explorer "commit" extension, when I try to the commit the folder(or any of the files within), no files show up in the dialogue. If I right click and commit a file within the folder, a pop up comes up that says "No files found for this operation". I am no Hg expert, although I have been using it for few months without a hitch, but I am pretty stuck on this one. Any ideas?</p>
  
  <p>UPDATE: I have added a screenshot below showing what happens when I try to add the new folder. None of the files in the folder seem to be recognized.</p>
