Adding a newline into as a header value puts all other headers into content body

[jappeace]

.. title

It happened when filling the bearer token of this libary: http://hackage.haskell.org/package/voicebase-0.1.1.1/docs/VoicebaseClient.html#v:transcribeBytes

Perhaps the bodies of header values should be url encoded?

It took me a long time to find that newline so I hope this will help someone.
