[question] Is it possible to remove newlines between `__future__`, `from` and `import`?

Attempting to use isort to style in the following manner:

• Individual imports on their own line.
• No sections; sort everything in alphabetical order but still respecting __future__ imports.

The closest configuration I can define to produce this is the following:

[isort]
force_alphabetical_sort = 1
force_single_line = 1
line_length = 9999
no_sections = 1

However, there are empty newlines injected between the __future__, from and import definitions. For example:

from __future__ import print_function
from __future__ import unicode_literals

from collections import defaultdict
from myproject import Entity
from os import path

import io

try:
    basestring
except NameError:
    basestring = str

I am hoping to produce output such as the following:

from __future__ import print_function
from __future__ import unicode_literals
from collections import defaultdict
from myproject import Entity
from os import path
import io

try:
    basestring
except NameError:
    basestring = str

I have tried the lines_* options to attempt to remove these newlines, but I have had no luck. Is there an option I am missing that can help achieve this?

Start with isort's documented configuration options, especially force_alphabetical_sort, no_sections, and the lines_* settings, then trace how future, from, and import statements are grouped. Confirm whether the requested output can be represented by existing configuration; if not, define the option behavior and add coverage for the two example layouts.
