patch 8.1.0043: ++bad argument of :edit does not work properly

commit https://github.com/vim/vim/commit/7580849df9d6c7c515f5ed784019336d8a8ec0f0

    patch 8.1.0043: ++bad argument of :edit does not work properly

    Problem:    ++bad argument of :edit does not work properly.
    Solution:   Return FAIL from get_bad_opt() only when there is no valid
                argument. (Dominique Pelle, Christian Brabandt, closes #2966,
                closes #2947)
