-S, --skip-string-normalization
Don't normalize string quotes or prefixes.
+ -N, --skip-numeric-underscore-normalization
+ Don't normalize underscores in numeric literals.
--check Don't write the files back, just return the
status. Return code 0 means nothing would
change. Return code 1 means some files would be
directories that should be excluded on
recursive searches. On Windows, use forward
slashes for directories. [default:
- build/|buck-out/|dist/|_build/|\.git/|\.hg/|
- \.mypy_cache/|\.nox/|\.tox/|\.venv/]

-q, --quiet Don't emit non-error messages to stderr. Errors
are still emitted, silence those with
2>/dev/null.

bother you if you overdo it by a few km/h".

Why settle on double quotes? They anticipate apostrophes in English

+An empty string in double quotes (`""`) is impossible to confuse with
a one double-quote regardless of fonts and syntax highlighting used.
On top of this, double quotes for strings are consistent with C which
Python interacts a lot with.
If you're running with `--verbose`, you will see a blue message if
a file was found and used.

### Protocol
`blackd` only accepts `POST` requests at the `/` path. The body of the request
-should contain the python source code to be formatted, encoded
+should contain the python source code to be formatted, encoded
according to the `charset` field in the `Content-Type` request header. If no
`charset` is specified, `blackd` assumes `UTF-8`.
There are a few HTTP headers that control how the source is formatted. These
correspond to command line flags for *Black*. There is one exception to this:
`X-Protocol-Version` which if present, should have the value `1`, otherwise the
-request is rejected with `HTTP 501` (Not Implemented).

The headers controlling how code is formatted are:
* cache is now populated when `--check` is successful for a file which speeds up
consecutive checks of properly formatted unmodified files (#448)
+* whitespace at the beginning of the file is now removed (#399)

+* fixed mangling [pweave](http://mpastell.com/pweave/) and
