Subject: vim-patch:8.2.2472: crash when using command line window in an
 autocommand

Problem:    Crash when using command line window in an autocommand.
            (houyunsong)
Solution:   Save and restore au_new_curbuf.
https://github.com/vim/vim/commit/aad5f9d79a2b71e9d2581eace3652be156102b9d

Nvim has removed :open, so use :edit in the test instead.
