title: "unadd" a file to svn before commit
body: <p>I was in the middle of doing a recursive svn add/commit, and a folder which did not have the proper ignore properties was included. I've got about 100 uploaded binary files versioned now, but I haven't committed yet.</p>
  
  <p>What is the easiest way to 'undo' this, without deleting all the documents?</p>
