Data Descriptors aren't properly captured

[barbester]

Problem Description

When a class attribute is implemented as a data descriptor, pdoc doesn't seem to be able to capture its docstring correctly.

For instance, put the code below into a module called descriptor.py and run pdoc on it.

class Descriptor():
    def __init__(self, func):
        self.__doc__ = func.__doc__

    def __get__(self, instance, owner):
        return self if instance is None else getattr(instance, "_x", 0)

    def __set__(self, instance, value):
        instance._x = value


class Dummy:
    @Descriptor
    def size(self):
        """This is the size"""

The result is like this:

i.e. the size attribute is correctly identified as a Descriptor instance, but its __doc__ is not captured.

---

Now remove method __set__ from the Descriptor class, so that it is a non-data descriptor. This changes the result to:

i.e. now the docstring is present.

Good catch, thanks for the detailed description! Could you please verify that #227 behaves as expected? 😃
