  An impossible-to-hit edge case today; we described the request
  as chunked - and if chunked always send the body termination "0"
  chunk header.

  Roy's requested change that we always send a body we could read
  in full as a C-L request ensures this code wasn't triggered; some
  change in the future could again reveal this edge case.
