You may need to restrict the tags you support; for instance, only
support links (<a href="URL">myurl</a>).  It's a lot harder for that
long a sequence to show up randomly than a simple <i>.

Another thing you can do is add code that recognizes uuencode and
base64 data, wraps it with <pre></pre>, but leave the data itself
unchanged.
