Indent of redbaron docstrings leaves trailing white spaces

[JohannesBuchner]

Adding a docstring adds indent, including on empty lines.

I am analysing and altering example.py:

def indicator(r, threshold=42):
    if r > threshold:
        return False
    else:
        return True

with the following code

import redbaron
rb = redbaron.RedBaron(open('gendocstr/example2.py').read())
docstring = """Hello world

how is it going?
"""
rb[0].value.insert(0, '"""%s"""' % docstring)
print(rb.dumps())

gives:

def indicator(r, threshold=42):
    """Hello world
    
    how is it going?
    """
    if r > threshold:
        return False
    else:
        return True

The line in the middle is also indented.

This causes linters to complain about trailing newlines.

As far as I can see, there is no way to control the automatic indentation.

This is with redbaron 0.9.2
