Line ending in raw request payload not consistent with headers

[drahnieR]

App Details:

Postman for Windows
Version 5.3.2
win32 10.0.15063 / x64

Issue Report:

1. Compose a POST request with raw/Text payload
2. Input some text with line breaks in the payload and send it.
3. Postman interprets the line breaks as "\n" in HTTP body, while uses "\r\n" in the header lines.

I think postman should translate line breaks according to OS, or at least, keep translation the same between headers and payloads.

@drahnieR Thanks for reporting this. I don't think I got you correctly. Do you have new lines in request headers as well ?

[drahnieR]

I have them, but the line feeds in headers are not consistent with line feeds in raw text body

from 01a0 starts the http body, all line feeds in body are '0a' only.

BTW, I know there's build-in mechanism that could be used to generate multipart requests. But what I want here is upload a tiny file without local file coupled.

@drahnieR We will prevent adding new lines to headers.
