Describe the style change

Unlike other expression level single element tuples, single element tuples in yield expressions (e.g. yield 1,) are currently not parenthesized. This is inconsistent, they should also be parenthesized.

Examples in the current Black style

Input:

for a, in b:
    pass

c = d,


def e():
    yield f,
    return g,

Output:

for (a,) in b:
    pass

c = (d,)


def e():
    yield f,
    return (g,)

Desired style

for (a,) in b:
    pass

c = (d,)


def e():
    yield (f,) 
    return (g,)
