vim-patch:8.2.0403: when 'buftype' is "nofile" there is no overwrite check

Browse Source 
Problem:    When 'buftype' is "nofile" there is no overwrite check.
Solution:   Also check for existing file when 'buftype' is set.
            (closes vim/vim#5807)
a3a9c8ef69

Nvim doesn't have buftype=popup and doesn't allow buftype=terminal for
non-terminal buffer.
