Formatting of `os.environ` wraps on the os.environ about blue HOT 2 CLOSED

I think it would be better if Black had chosen:

os.environ['JAVA_HOME'] = (
    '/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/'
)

But it can't do that because introducing the parens would change the AST (which it strictly forbids as a sanity check so that it doesn't change semantics).

You're options then are to:

1. Disable formatting somehow on this line (e.g. #28)
2. Change the diff yourself to use parens. (Black/Blue won't complain then.)
3. Increase the line length.
4. Introduce a variable like:

java_home_path = '/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/'
os.environ['JAVA_HOME'] = java_home_path

But I don't see anything blue or black could otherwise do here (while still adhering to the line-length rule and no-ast-changes rule).

from blue.

Bummer, but I agree with your analysis.
