Correctly handle inline tabs in docstrings (#1810)
The `fix_docstring` function expanded all tabs, which caused a
difference in the AST representation when those tabs were inline and not
leading. This changes the function to only expand leading tabs so inline
tabs are preserved.

Automatically build and upload binaries on release (#1743)
This commit adds a new GitHub Actions workflow that builds self-contained
binaries / executables and uploads them as release assets to the triggering
release. Publishing a release, drafting one doesn't count, will trigger this
workflow.
I personally used GitHub Actions only because it's the CI/CD platform(?)
I am familiar with. Only Windows and Linux binaries are supported since
I don't have any systems running Mac OS.
For Linux, I had originally planned to use the manylinux2010 docker image
the PyPA provides for highly compatible wheel building, but unfortunately
it wasn't feasible due to GitHub Actions and PyInstaller incompatibilities.
As a stopgap the oldest versions of Linux and Windows are used although
Windows Server 2019 isn't that old nor is Ubuntu 16.04! I guess someone
(maybe me) could work out something else if compatibility is big problem.
A few things you should know about the workflow:
- You don't need to set the `GITHUB_TOKEN` secret as it is automatically
provided by GitHub.
- matrix.pathsep is used because PyInstaller configuration's format is OS
dependent for some reason ...
Also it's worth mentioning that Black once had Travis CI and AppVeyor
configuration that did the same thing as this commit. They were committed
in mid 2018 and worked (somewhat) well. Eventually we stopped using AppVeyor
and the refactor to packages broke the Travis CI config. This commit
replaces the still existing and broken Travis CI config wholesale.

- Anders told me that I could get the release asset upload URL directly
from the github.event.release payload. I originally planned to use
bruceadams/get-release to get such URL.

Repair colorama wrapping on non-Windows platforms (#1670)
* Repair colorama wrapping on non-Windows platforms
The wrap_stream_for_windows() function calls
colorama.initialise.wrap_stream() function to apply colorama's magic to
wrapper to the output stream. Except this wrapper is only applied on
Windows platforms that need it, otherwise the original stream is
returned as-is.
The colorama wrapped stream lacks a detach() method, so a no-op lambda
was being assigned to the wrapped stream.
The problem is that the no-op lambda was being assigned unconditionally
whether or not colorama actually returns a wrapped stream, thus
replacing the original TextIOWrapper's detach() method. Replacing the
detach() method with a no-op lambda is the root cause of the problem
observed in #1664.
The solution is to only assign the no-op detach() method if the stream
lacks its own detach() method.

Fix empty line handling when formatting typing stubs (#1646)
Black used to erroneously remove all empty lines between non-function
code and decorators when formatting typing stubs. Now a single empty
line is enforced.
I chose for putting empty lines around decorated classes that have empty
bodies since removing empty lines around such classes would cause a
formatting issue that seems to be impossible to fix.
For example:
```
class A: ...
@some_decorator
class B: ...
class C: ...
class D: ...
@some_other_decorator
def foo(): -> None: ...
```
It is easy to enforce no empty lines between class A, B, and C.
Just return 0, 0 for a line that is a decorator and precedes an stub
class. Fortunately before this commit, empty lines after that class
would be removed already.
Now let's look at the empty line between class D and function foo. In
this case, there should be an empty line there since it's class code next
to function code. The problem is that when deciding to add X empty lines
before a decorator, you can't tell whether it's before a class or a
function. If the decorator is before a function, then an empty line
is needed, while no empty lines are needed when the decorator is
before a class.
So even though I personally prefer no empty lines around decorated
classes, I had to go the other way surrounding decorated classes with
empty lines.

Fix incorrect space before colon in if/while stmts (#1655)
* Fix incorrect space before colon in if/while stmts
Previously Black would format this code
```
if (foo := True):
print(foo)
```
as
```
if (foo := True) :
print(foo)
```
adding an incorrect space after the RPAR. Buggy code in the
normalize_invisible_parens function caused the colon to be wrapped in
invisible parentheses. The LPAR of that pair was then prefixed with a
single space at the request of the whitespace function.
This commit fixes the accidental skipping of a pre-condition check
which must return True before parenthesis normalization of a specific
child Leaf or Node can happen. The pre-condition check being skipped
was why the colon was wrapped in invisible parentheses.

Fix multiline docstring quote normalization
The quotes of multiline docstrings are now only normalized when string
normalization is off, instead of the string normalization setting being
ignored and the quotes being *always* normalized.
I had to make a new test case and data file since the current pair for
docstrings only worked when there is no formatting difference between the
formatting results with string normalization on and off. I needed to add
tests for when there *are* differences between the two. So I split
test_docstring's test code when string normalization is disabled into a
new test case along with a new data file.

Address pre-existing trailing commas when not in the rightmost bracket pair
This required some hackery. Long story short, we need to reuse the ability to
omit rightmost bracket pairs (which glues them together and splits on something
else instead), for use with pre-existing trailing commas.
This form of user-controlled formatting is brittle so we have to be careful not
to cause a scenario where Black first formats code without trailing commas in
one way, and then looks at the same file with pre-existing trailing commas
(that it itself put on the previous run) and decides to format the code again.
One particular ugly edge case here is handling of optional parentheses. In
particular, the long-standing `line_length=1` hack got in the way of
pre-existing trailing commas and had to be removed. Instead, a more
intelligent but costly solution was put in place: a "second opinion" if the
formatting that omits optional parentheses ended up causing lines to be too
long. Again, for efficiency purposes, Black reuses Leaf objects from blib2to3
and modifies them in place, which was invalid for having two separate
formattings. Line cloning was used to mitigate this.

Re-implement magic trailing comma handling:
- when a trailing comma is specified in any bracket pair, that signals to Black
that this bracket pair needs to be always exploded, e.g. presented as "one
item per line";
- this causes some changes to previously formatted code that erroneously left
trailing commas embedded into single-line expressions;
- internally, Black needs to be able to identify trailing commas that it put
itself compared to pre-existing trailing commas. We do this by using/abusing
lib2to3's `was_checked` attribute. It's True for internally generated
trailing commas and False for pre-existing ones (in fact, for all
pre-existing leaves and nodes).

Make --exclude only apply to recursively found files (#1591)
Ever since --force-exclude was added, --exclude started to touch files
that were given to Black through the CLI too. This is not documented
behaviour and neither expected as --exclude and --force-exclude now
behave the same!
Before this commit, get_sources() when encountering a file that was passed
explicitly through the CLI would pass a single Path object list to
gen_python_files(). This causes bad behaviour since that function
doesn't treat the exclude and force_exclude regexes differently. Which
is fine for recursively found files, but *not* for files given through
the CLI.
Now when get_sources() iterates through srcs and encounters
a file, it checks if the force_exclude regex matches, if not, then the
file will be added to the computed sources set.
A new function had to be created since before you can do regex matching,
the path must be normalized. The full process of normalizing the path is
somewhat long as there is special error handling. I didn't want to
duplicate this logic in get_sources() and gen_python_files() so that's
why there is a new helper function.

expression tests: adjust starred expression for Python 3.9 (#1441) (#1477)
As discussed in #1441, Python 3.9's new parser will not parse
`(*starred)` even using `compile()` with the `PyCF_ONLY_AST`
flag (as `ast.parse()` does), it raises a `SyntaxError`. This
breaks the four tests that use this file with Python 3.9.
Upstream does not consider this to be a bug - see
https://bugs.python.org/issue40848#msg370643 - so we must
adjust the expression. As suggested by @JelleZijlstra, this just
adds a comma, which makes the new parser happy with it (the old
parser is fine with this form also).
