Keyword-only arguments without defaults are treated as positionals

[evanunderscore]

import defopt
def test(*, a):
    """:param str a: test"""
defopt.run(test, argv=['-h'])

usage: do.py [-h] a

positional arguments:
  a           test

optional arguments:
  -h, --help  show this help message and exit

This was an oversight, but my actual words from the documentation are "any optional arguments are converted to flags", so this is presently working as documented, even if not as intended. This means a fix should come with a major version bump.
