Odd formatting with split ternary in dict literal

[ojii]

Operating system: mac OS 10.13.4 (High Sierra)
Python version: 3.6.5
Black version: 1445bea
Does also happen on master: Yes

Given this input:

data = {
    "a": compute_a_value_this_is_so_long() if some_condition_long_condition else compute_another_value(),
    "b": 10
}

Black gives me:

data = {
    "a": compute_a_value_this_is_so_long()
    if some_condition_long_condition
    else compute_another_value(),
    "b": 10,
}

The if and else on the same indentation level as the keys looks very odd and hard to parse at a glance to me. Moving it up one level and possibly adding parens makes it easier to read/prettier to me.

data = {
    "a": (
        compute_a_value_this_is_so_long()
        if some_condition_long_condition
        else compute_another_value()
    ),
    "b": 10,
}

Of course this is not the only solution and maybe others think the current code is okay. Just my 2 cents.

Thanks for reporting! This looks like it boils down to the same issue as #147
