No description provided.

Could you redo the commit message and provide a description? The class is dummy_ctype, not sure what dunder is. Also take a look at doc/source/dev/gitwash/development_workflow.rst to see the correct prefixes for the commit summary line. I think here BUG: is probably correct, as the documentation suggests that both __eq__ and __ne__ should be explicitly defined.

Done. dunder = double underscore 😃

Looks good, but the commit message still needs improvement. All lines should be <=72 characters in length, and the summary even shorter if possible. There are plugins for different editors that help with git commit messages. Anyway, something like

BUG: add `__ne__`  method to dummy_ctype class.

There is no Python defined relation between `__eq__` and `__ne__`,  so it is
recommended that both be defined.

Appveyor error is http timeout, so merging this. Thanks @srinivasreddy .
