**The output is always streamed** unless ``--pretty`` is set or implied. You
can use ``--stream`` / ``-S`` to enable streaming even with ``--pretty``, in
which case every line of the output will processed and flushed as soon as it's
avaialbe (as opossed to buffering the whole response which wouldn't work for
long-lived requests). You can test it with the Twitter streaming API:
.. code-block:: shell
http -Sfa <your-twitter-username> https://stream.twitter.com/1/statuses/filter.json track='Justin Bieber'
# \/
# The short options for --stream, --form and --auth.
``--stream`` can also be used regardless of ``--pretty`` to ensure a more
frequent output flushing (sort of like ``tail -f``).

=========
* `0.2.7dev`_
* Streamed terminal output. ``--stream`` / ``-S`` can be used to enable
streaming also with ``--pretty`` and to ensure a more frequent output
flushing.
* Support for efficient large file downloads.
* Response body is fetched only when needed (e.g., not with ``--headers``).
* Improved content type matching.

The body can be binary so we always yield `bytes`.
message = BINARY_SUPPRESSED_NOTICE
If `prettifier` is set or the output is a terminal then a binary
body is not included in the output and is replaced with notice.
Generally, when the `stdout` is redirected, the output matches the actual
message as much as possible (formatting and character encoding-wise).
When `--pretty` is set (or implied), or when the output is a terminal,
then we prefer readability over precision.
