Description

Show function:

function(doc,req){
  return {"json": true}
}

Curl command:

curl -v  http://localhost:5984/db/_design/test/_show/json -H "Accept: application/json"

Note line in response with:

Content-Type: application/json, application/json

While it's ok for HTTP, I believe there should be only one "application/json" MIME type.
