Subject: vim-patch:8.2.0911: crash when opening a buffer for the cmdline
 window fails

Problem:    Crash when opening a buffer for the cmdline window fails. (Chris
            Barber)
Solution:   Check do_ecmd() succeeds.  Reset got_int if "q" was used at the
            more prompt. (closes vim/vim#6211)
https://github.com/vim/vim/commit/9b7cce28d568f0622d77c6c9878c2d4770c3b164

Make code match latest Vim instead.
