[docs] [issue18456] Documentation for PyDict_Update is incorrect

[Nick Coghlan]

New submission from Nick Coghlan:

The docs from PyDict_Update (http://docs.python.org/3/c-api/dict.html#PyDict_Update) claim it is equivalent to the Python level dict.update (http://docs.python.org/3/library/stdtypes#dict.update)

This isn't accurate - unlike dict.update, PyDict_Update doesn't fall back to the iterating over a sequence of key value pairs if the second argument has no "keys" attribute.
