title: Delete file contents from SVN history
body: <p>I have a local svn repository in my PC, I have been using it for a hobby project and it wasn't meant to be accessible to anyone, so I commited files with passwords in them.</p>
  
  <p>Now, I'm thinking of making the repository available for other people and I don't want to have that data there.</p>
  
  <p>Is there a way to crawl the repository and replace all the passwords and account data with a text like "xxxxxxxxxx"?</p>
