Bulk query gives error

[karl-sjogren]

I'm trying out a bulk-query as follows.

POST _bulk
{ "index" : { "_index" : "esdemo-reviews"} }
{ "title": "22/11 1963", "by": "King, Stephen", "reviewer": "Sonja Viklund", "preamble": "En man reser femtio år tillbaka i tiden för att försöka skriva om historien och hindra mordet på John F Kennedy." }
{ "index" : { "_index" : "esdemo-reviews"} }
{ "title": "4.50 från Paddington", "by": "Christie, Agatha", "reviewer": "Helen Forsberg", "preamble": "När polisen inte lyssnar på mrs McGillicuddy när hon vill rapportera ett mord, vänder hon sig till sin vän miss Marple." }

But when I run it I get an error about a missing new line at the end of the request.

The same also happens if I try the query from the demo repo.
