Possible to set filetype for vim ($EDITOR) launched by nnn?

[csswright]

EDIT: workaround that works, curious if there's a better solution:

Instead of nnn -E trying to use EDITOR="nvim +set filetype=rename" (which doesn't work), set EDITOR=nvim-wrapper and have the wrapper script run exec /usr/bin/nvim +"set filetype=rename" "$@".

When renaming files with nnn with vim (neovim), I want to set that filetype to something specific like rename (set ft=rename). This is useful because I use a completion source containing a dictionary list of names to complete that I only want to trigger for this filetype or instance of vim launched by nnn (I don't normally want this set of completion items in other filetypes). I don't want to manually set this filetype or enable dictionary list every time in order to activate this completion.

I tried editing $EDITOR to e.g. nvim +set filetype=rename and using nnn's -E option but the +set filetype=rename args to nvim are not parsed correctly (not that I expect to, just an idea).

Another idea is to use modeline feature to set filetype, but that would make less sense for nnn to support.
