title: Subversion ignoring "--password" and "--username" options
body: <p>When I try to do any svn command and supply the <code>--username</code> and/or <code>--password</code> options, it prompts me for my password anyways, and always will attempt to use my current user instead of the one specified by <code>--username</code>. Neither <code>--no-auth-cache</code> nor <code>--non-interactive</code> have any effect on this. This is a problem because I'm trying to call svn commands from a script, and I can't have it show the prompt.</p>
  
  <p>For example, logged in as user1:</p>
  
  <pre><code># $ svn update --username 'user2' --password 'password'
  # user1@domain.com's password: 
  </code></pre>
  
  <p>Other options work correctly:</p>
  
  <pre><code># $ svn --version --quiet
  # 1.3.2
  </code></pre>
  
  <p>Why does it prompt me?<br>
  And why is it asking for user1's password instead of user2's?<br>
  I'm 99% sure all of my permissions are set correctly. Is there some config option for svn that switches off command-line passwords?<br>
  Or is it something else entirely?</p>
  
  <p>I'm running svn 1.3.2 (r19776) on Fedora Core 5 (Bordeaux).</p>
