Enhancement request

The output from the CLI seems to always include 2 trailing empty lines. Could they be removed?

Example command: $ https google.com

Current output:

The output I would like:

So exactly the same, and still with an empty line for padding between sections like headers and body, but without the 2 trailing empty lines.

Problem it solves

Would give a shorter output. This means there would be a shorter distance to scroll up to some output, and in some cases there would be no need to scroll at all, since more actual output could fit in the window.

Additional information, screenshots, or code examples

cli/httpie/output/writer.py

Lines 22 to 26 in 9e8e369

    
           MESSAGE_SEPARATOR = '\n\n' 
        
           MESSAGE_SEPARATOR_BYTES = MESSAGE_SEPARATOR.encode()

These lines append two newlines at the end of the output. I also thinks that it should append only a single newline.
