Fix regression: unexpected parentheses around non-mathematical powers 
This was caused by an overly liberal application of parentheses in #909 that
fixed #646.

Back out #850 (#1079) 
Fixes #1042 (and probably #1044 which looks like the same thing).

The issue with the "obviously unnecessary" parentheses that #850 removed is that sometimes they're necessary to help Black fit something in one line. I didn't see an obvious solution that still removes the parens #850 was intended to remove, so let's back out this change for now in the interest of unblocking a release.

This PR also adds a test adapted from the failing example in #1042, so that if we try to reapply the #850 change we don't break the same case again.

0ff718e1e2 Blacken .py files in blib2to3 (#1011) 
* Blacken .py files in blib2to3

This is in preparation for adding type annotations to blib2to3 in
order to compiling it with mypyc (#1009, which I can rebase on top of
this).

To enforce that it stays blackened, I just cargo-culted the existing
test code used for validating formatting. It feels pretty clunky now,
though, so I can abstract the common logic out into a helper if that
seems better. (But error messages might be less clear then?)

* Tidy up the tests

7b11f04d54 Fix type: ignore line breaking when there is a destructuring assignment (#1065) 
It turns out we also need to handle invisible *left* parens added at
the *start* of a line. Refactor `contains_unsplittable_type_ignore` to
handle this more cleanly.

1336094634 Fix missed cases in the # type: ignore logic (#1059) 
In #1040 I had convinced myself that the type ignore logic didn't
need anything like the ignored_ids from the type comment logic, but I
was wrong, and we do.

We hit these cases in practice a bunch.

6fe800933d Fix issue with type comments on lines with trailing commas (#1058) 
The code introduced in #1027 to detect whether a type comment appeared
after a regular comment in a Line would spuriously misfire when a leaf
was in the comments dict but had an empty list of comments. This can
occur as an artifact of how comments on trailing commas are handled,
it seems.

(This was discovered trying to test black out on mypy.)

0c44220e21 Don't allow type comments to be merged behind regular comments (#1027) 
Type comments only apply if they are the first comment on the line,
which means that allowing them to be pushed behind a regular comment
when joining lines is a semantic change (and, indeed, one that black
catches and fails on).

Move tokenizer config onto grammar, rename flag

- Remove TokenizerConfig, and add a field to Grammar instead.
- Pass the Grammar to the tokenizer.
- Rename `ASYNC_IS_RESERVED_KEYWORD` to `ASYNC_KEYWORDS` and
  `ASYNC_IS_VALID_IDENTIFIER` to `ASYNC_IDENTIFIERS`.

Add support for always tokenizing async/await as keywords 
Fixes #593

I looked into this bug with @ambv and @carljm, and we reached the
conclusion was that it's not possible for the tokenizer to determine if
async/await is a keyword inside all possible generators without breaking
the grammar for older versions of Python.

Instead, we introduce a new tokenizer mode for Python 3.7+ that will
cause all async/await instances to get parsed as a reserved keyword,
which should fix async/await inside generators.

227c2d77b4 Changes default logger used by blib2to3 Driver (#732) 
... to stop it from spamming the log when black is used as a library in another
    python application.

When used indirectly by black the logger initiated in `driver.py` will emit
thousands of debug messages making the debug level of the root logger virtually
useless. By getting a named logger instead the verbosity of logging from this
module can easily be controlled by setting its log level.

I ended up making a couple of other normalizations to numeric literals

remove redundant + sign in exponent). I don't care too much about those,
so I'm happy to change the behavior there.

For reference, here is Python's grammar for numeric literals:

51756a405c Added --include and --exclude cli options (#281) 
These 2 options allow you to pass in regular expressions that determine
whether files/directories are included or excluded in the recursive file

5a47fd13cc Don't use optional parentheses in unnecessary situations 
If an expression starts or ends with a bracket and only contains a single
delimiter, don't wrap it in additional optional parentheses.  We can use the
brackets for the split.

1747c388bb Discover whether a file is Python 3.6+ also by stars in calls 
Fixes a pathological situation where if a function signature used a trailing
comma but was later reformatted to a single line (with the trailing comma
removed), Black would change its mind whether a file is Python
3.6-compatible between runs.

2d9eaafa97 Output something when no files are reformatted (#190) 
Just executing ``black`` without any argument does not print any message
to stdout or stderr. It's rather confusing, because the user doesn't
know what happened.

In ``len(sources) == 0`` case, black now prints ``No paths given. Nothing to
do``.
