Is the concatenating lines with strings intended like this?

Operating system: Arch Linux
Python version: 3.6
Black version: 18.4a4
Does also happen on master: dunno - I don't even know if it is a bug or a feature yet.

With default line length black turns

fmt = (
    "%(asctime)s %(filename)s.%(funcName)s:%(lineno)d %(levelname)s: "
    "%(message)s"
)

into

fmt = (
    "%(asctime)s %(filename)s.%(funcName)s:%(lineno)d %(levelname)s: " "%(message)s"
)

I would expect to either leave it alone or concatenate the strings like:

fmt = (
    "%(asctime)s %(filename)s.%(funcName)s:%(lineno)d %(levelname)s: %(message)s"
)

Is this behaviour intended?

Yes, in the future black will be able to merge these strings, see #26 for some more discussion around this

Hi @zsol thanks, I missed that one, when looking for open issues.
