False positives for multiline strings

[phihag]

I have a file with the content

s = (
    'this' +
    'is a string'
)
print(s)

and another with

s = (
    'this'
    'is a string'
)
print(s)

Both files emit a warning

t.py:3:18: C812 missing trailing comma

This warning dangerous, since actually adding a comma changes the meaning of the statement!

@phihag fixed in 0.2.0

Would it be possible to add an optional check to flag multiline strings as errors? In my code base we never use multiline strings and I would like to catch missing commas in lists.
