* Also add a possible ETag header to r->headers_out. We need to have it there

  for our later call to ap_meets_conditions a few lines above. Having it put
  in the merge table will fail as merge and r->err_headers_out get merged
  AFTER our call to ap_meets_conditions. Besides of this having multiple
  ETag headers (or a merged version of them) does not seem to make sense.
