[issue14634] Mock cannot autospec functions with keyword-only arguments.

[Michael Foord]

Michael Foord <michael at voidspace.org.uk> added the comment:

This is non-trivial to fix. Although inspect.getfullargspec can be used, which does support keyword only arguments, inspect.formatargspec *doesn't* support them. (mock.create_autospec uses these to rebuild a compatible signature for generated mocks.)

The easiest route to fixing would be to extend formatargspec to optionally take extra arguments for kwonlyargs and kwonlydefaults.
