\n is not an acceptable key value?

[keko950]

Hi! Im having some troubles with multilines values. Im trying to add a key that has as content multiple \n but it doesn't work and im not sure why.

You can reproduce the error with this simple code:
a = configobj.ConfigObj(infile=['a="""line1 \n line2 \n line3"""'])

lib/python3.8/site-packages/configobj.py", line 1318, in _load
    raise error
configobj.ParseError: Invalid line ('a="""line1 \n line2 \n line3"""') (matched as neither section nor keyword) at line 1.

The next action is to see if still happens with other string literals (or something more dynamic), based on that, I'll determine if this is more bug or more documentation
