That can be much harder than typing ctrl-SPC. It *is* supported by
netcat, for example, but then you have to carefully recompute the
content-length field.

If I terminated the input, I wouldn't need any framing. The point is to
carry a number of JSON messages/documents over a single bytestream or in
a single file. That means the HTTP content-length would be mandatory.
