title: svn propedit gives me a blank file
body: <p>I know that the <code>svn:ignore</code> property is populated in my working copy, but when I do</p>
  
  <pre><code>svn propedit svn:ignore . --editor-cmd notepad
  </code></pre>
  
  <p>I get a blank file; editing and saving the blank file has no effect on the property.  Using other editors gives a similar result.</p>
  
  <p>Why isn&#8217;t this working?</p>
  
  <p>I am using a 1.4.2 server and a 1.6.6 client on Windows XP.</p>
  
  <h3>Update</h3>
  
  <p>I have tried Notepad, UltraEdit-32, and Sublime Text, with and without the <code>start /wait</code> command, and not gotten anything to work.  I <em>have</em> gotten it to work on a Debian machine, just not on Windows XP.  Can anyone provide an example of a command that has the desired result, or a setting that I need to change in Windows?</p>
