long subscript expressions

Describe the style change

It doesn't make sense to me that a dictionary key should go on its own line. There should be a different way to format what is below to improve readability.

Examples in the current Black style

blah = blahaoeuuisndthaoheinthoaeusnthaoeusnhoeausthnoeusnthtsthnoaeustnh["blah"][
    "blah"
]

Desired style

blah = (
    blahaoeuuisndthaoheinthoaeusnthaoeusnhoeausthnoeusnthtsthnoaeustnh["blah"]["blah"]
)

Additional context Add any other context about the problem here.

While the duplication in this area is absolutely ridiculous, I'll be closing this as a duplicate of #1280.
