Will release the test case for thees soon, the test case for thees still have many (so many) bugs.

But when I think about it again, isn't Black spouse to do this thing for us?
I don't talk about actually concatenating the strings, they made it very clear that they're not going to do so here (that's why we have #30467).
I mean, just putting them together (the strings), Black is already concatenating the strings with "easy" strings like:

msg = (
     "foo "
     "bar "
     "baz "
)

to

msg = ("foo " "bar " "baz")

But when it comes to strings with more characters it won't change them.

For example, Black is not going to change this (even if the line length is below 88) :

def func():
    msg = (
        "foo foo foo foo foo foo foo foo foo "
        "bar bar bar bar bar bar bar bar bar "
        "baz"
    )

to this:

def func():
    msg = (
        "foo foo foo foo foo foo foo foo foo "
        "bar bar bar bar bar bar bar bar bar " "baz"
    )

---

Is there a feature of Black we are missing?

@MomIsBestFriend I don't want to speak for black but not sure it's that big of a deal. Sometimes readability can be improved by breaking at particular points in the string rather than always trying to pad to 88 characters

OK to continue along with f-string replacement but I don't think its a goal to always pad strings to their fullest length on a line, so maybe not worth investing a ton of time into

@WillAyd You have a very good point.
