If I have this statement assigning a lambda, which returns a multiline string, to a variable:

x = lambda: """
        a
    b
"""

The automatic fix turns it into

def x():
    return "\n        a\n    b\n"

This technically preserves the whitespace correctly, but destroys readability.

I don't know if it is possible, but it would be great, if the fix could preserve the original multiline string:

def x():
    return """
        a
    b
"""
