+ --pyi Consider all input files typing stubs regardless

+ --py36 Allow using Python 3.6-only syntax on all input

+ -S, --skip-string-normalization
+ Don't normalize string quotes or prefixes.

imports cannot fit in the allotted length, it's always split into one
element per line. This minimizes diffs as well as enables readers of
code to find which commit introduced a particular entry. This also

### Line length
It will also insert proper spacing before and after function definitions.
It's one line before and after inner functions and two lines before and
-after module-level functions. *Black* will not put empty lines between
-function/class definitions and standalone comments that immediately precede
-the given function/class.
+after module-level functions and classes. *Black* will not put empty
+lines between function/class definitions and standalone comments that
+immediately precede the given function/class.
+
+*Black* will enforce single empty lines between a class-level docstring
+and the first following field or method. This conforms to
+[PEP 257](https://www.python.org/dev/peps/pep-0257/#multi-line-docstrings).
+
+*Black* won't insert empty lines after function docstrings unless that
+empty line is required due to an inner function starting immediately
+after.
### Trailing commas
key. My recommendation here is to keep using whatever is faster to type
and let *Black* handle the transformation.
+If you are adopting *Black* in a large project with pre-existing string
+conventions (like the popular ["single quotes for data, double quotes for
+human-readable strings"](https://stackoverflow.com/a/56190)), you can
+pass `--skip-string-normalization` on the command line. This is meant as
+an adoption helper, avoid using this for new projects.

### Vim
create a virtualenv manually and point `g:black_virtualenv` to it.
The plugin will use it.
+To run *Black* on save, add the following line to `.vimrc` or `init.vim`:
+
+```

**How to get Vim with Python 3.6?**
On Ubuntu 17.10 Vim comes with Python 3.6 by default.
On macOS with Homebrew run: `brew install vim --with-python3`.
