long strings are not broken into small chunks

[098799]

Howdy! Sorry you're having trouble. To expedite your experience,
provide some basics for me:

Operating system:
Python version: 3.6.5
Black version: 18.6b4
Does also happen on master: yes

To answer the last question, you have two options:

1. Use the online formatter at https://black.now.sh/?version=master, which will use the latest master branch.
2. Or run black on your machine:
   • create a new virtualenv (make sure it's the same Python version);
   • clone this repository;
   • run pip install -e .;
   • make sure it's sane by running python setup.py test; and
   • run black like you did last time.

Long strings are not broken into small chunks, therefore violating the 88 character in a line rule (or even 120 if the string is long enough). I'd expect a utility as this one to be aware of line limits and create a following type of break

("somestringthatisverylongsomestringthatisverylongsomestringthatisverylong"
"yes it's really really long yes it's really really long yes it's really really long")

You're right, black doesn't do this yet. It's probably going to do it in the future, #182 tracks this
