<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Thanks for the suggestions so far. These are interesting but they<br>
require retrofitting scripts, so aren't universally compatible with<br>
any ck ever written (which I hope you agree would be super super<br>
helpful). Is there no solution that requires no change to the ck to be<br>
converted?<br>
