1. Works now, Thanks!

   2. Not sure how it worked without the "cons", but that code was written
   from memory in 2012, or thereabouts -- so even if we insist on the
   cons if it's the right thing, it's likely it might break other code
   out there.

   3. Finally, we may not be completely done, though searches now work,
      closing the ephemeral group when done causes emacs to hang -- here
      is a backtrace generated by setting debug-on-quit to t  and
      hitting C-g.
