Spellchecker doesn't ignore labels and types in autodoc docstrings

[avylove]

Current problem

There are a few styles of these (Google, Numpy) but the project I'm working on uses a style like this. I guess this would be Sphinx style?

def func(argname1, argname2):
    '''
    :arg str argname1: Description of `argname1`
    :arg int OrderedDict: Description of `argname2`

    :rtype: str
    :returns: Description of return value.
    '''
    ...

arg, rtype, str all come up as spelling errors. Interestingly OrderedDict doesn't unless I specify it as collections.OrderedDict

The current workaround it to add these to the ignored words list or private dictionary, but that can potentially lead to masking other spelling errors. The bigger issue is this creates resistance to using the spell checker, especially with those who aren't used to it.

Desired solution

The spell checker should be able to recognize these cases and ignore them, but not ignore the the description text to the right. Potentially this could be configurable like spelling-ignore-comment-directives, but these styles don't change at the frequency of new tools being introduced.
