Sorry that I'm only mentioning this now, but is there any reason to use
`dict(urlparse.parse_qsl(query))` instead of `urlparse.parse_qs(query)`? It
seems that there would only be a difference in cases with multiple values for
the same query parameter and arguably `parse_qs` behaves better in such case (it
doesn't discard all values except for the last, but makes lists of values
instead).

You are right - Done.

This function name is a bit unclear, probably `crowdin_body_and_headers` would
be better. Or even better and more "in the language of the domain" we could call
it something like `crowdin_prepare_upload`.

[tlucas, 2017/09/28 15:53:40]

Fair enough - Done.

[Vasily Kuznetsov, 2017/09/28 14:35:00]

I think "matching" instead of "according" would be better here.

Done.
