small bug in 'class Appender'

[cgringmuth]

I think there is small bug in the Appender class in docstring.py module?

# version with error
def __call__(self, func):
    docitems = [func.__doc__, self.addendum]
    func.__doc__ = func.__doc__ and ''.join(docitems) # <- here is there error
    return func

# corrected version
def __call__(self, func):
    docitems = [func.__doc__, self.addendum]
    func.__doc__ = func.__doc__ and self.join.join(docitems) # corrected version
    return func

I have tested the corrected version and my correction works as expected.

Can you please put that in a PR?

[cgringmuth]

sorry, i'm not sure what do you mean by PR?

EDIT -- sorry, the comment was too fast. You asked me to make a Pull Request ;)

sorry, I fall into jargon far too easily.

no problem... i figured that out and already made an pull request. the mistake was very small, so only one line has to be changed in order to work properly again. now the docstrings which are generated with the Appender class are working as normal ;)
