parameter types should be rendered as references

[anntzer]

Consider
pkg/__init__.py

class C:
    """Some class.
    """


def func(x):
    """Some function.

    Parameters
    ----------
    x: C
        The x.
    """

pkg.rst

pkg package
===========

Module contents

.. automodule:: pkg
    :members:
    :undoc-members:
    :show-inheritance:

In the parameter list of func, numpydoc ultimately renders C (could also be pkg.C or ~pkg.C, all without backquotes in the docstring) in bold, whereas sphinx.ext.napoleon renders C as a reference to the C class (with a link). The latter behavior appears to be more useful.

One may argue that "C" should be enclosed in backquotes for that to happen, but in fact sphinx's default info field list syntax (http://www.sphinx-doc.org/en/stable/domains.html#info-field-lists) also does not require backquotes (similarly to numpydoc's examples) but still renders "C" as a reference.

(Actually looks similar to #43, #57 but possibly with more background info. In particular it would be nice if ~pkg.C and .pkg.C are correctly handled. Feel free to close as duplicate.)

I can't see where this logic appears in Napoleon's source code... I'm a bit befuddled.
