title: VS2013 Git -- Cannot complete the operation because of existing changes to the following file
body: <p>Using VS 2013, I have made a change to a file, successfully committed and pushed to the server.  When I go to change to a different branch, I get the following error:</p>
  
  <p><strong>Cannot switch to CM because there are uncommitted changes. Commit or undo your changes before you switch branches. See the Output window for details.</strong></p>
  
  <p>The output window of course shows the file I just committed and pushed.  There are no files listed in the "Changes" area.</p>
  
  <p>SourceTree shows no unstaged files and lets me change branches without a problem.</p>
  
  <p>Any ideas?</p>
