title: Deleted files locally but cannot push changes to heroku
body: <p>I had some files that were messing up my Heroku app so I decided to delete them locally.  When I tried to push the changes to Heroku, it says that the files were deleted but there were no changes to commit.  Also when I ran git push heroku master, it said everything was up to date although my commit showed that there were deleted files.  How can I push these changes or delete them from the repository?  Thanks for your help!</p>
