Revision 562

   * Fixed noninteractive note element to not let the shell get its grubby
     little hands on unvalidated input, which was making it puke.
     Closes: #77589 and a whole raft of other bugs filed against X which we
     will be merging to it. Special thanks to Ingo Saitz for providing many
     debug logs, and the person I've forgot who should delete my debug
     account from their box now.
