True, I haven't had issues with json tools regarding a (lack of) 
terminating newlines. Some tools like jshon do have an issue with 
several requests pasted together, unless you insert some commas. In that 
sense I wondered on how the RPC terminates its output, and how it may do 
so in the future.

Of course, if/when we get POST requests [1], you no longer have to think 
on merging JSON. :)
