Vim -- how to control formatoptions when opening up a file with no filetype?

i have my formatoptions set like this in my ~/.vimrc: 

set formatoptions=caq1njw

Sometimes I run a script which lets me edit a temporary plain-text file which has paths that begin with // (They are perforce file paths).

This causes vim to apply wrapping comment paragraph rules so if I have a few short file paths that add up to less than textwidth characters long, it will merge the file paths while I edit this file list! This would be super extra bad.

Now I know how to get Vim to apply different settings upon opening different filetypes by using the .vim/after/ftplugin. For instance if I wanted formatoptions to be something specific for javascript files I would edit some ftplugin/javascript.vim file, as evidenced by this: 

:verbose set formatoptions
  formatoptions=a1njwcroql
        Last set from ~/bin/share/vim/vim73/ftplugin/javascript.vim
Press ENTER or type command to continue

(my vim is installed under ~/bin, yeah, this is unconventional)

So it looks like the bundled javascript.vim is applying l and r in addition to my .vimrc's caq1njw. That's fine, I can configure vim's behavior for javascript however I want.

But what I want is for plain, normal, undetected filetype files to NOT use caq1njw. And, for all other recognized filetypes to use caq1njw.

Is there a way to do this without adding set formatoptions=caq1njw to each and every filetype that I use?

Basically some sort of ftplugin/vanilla.vim that is run only when the filetype is undetected.

In case that temporary plain-text file follows any (path and/or filename) pattern, I'd define an autocmd on that:

:autocmd BufNew,BufRead /tmp/tempfile*.tmp setlocal formatoptions=...

For the general case, it's difficult to trigger on the FileType event not being thrown. You'd have to use another event that comes after that, e.g.:

:autocmd BufWinEnter * if empty(&l:filetype) | setlocal formatoptions=... | endif

I'd go with the first alternative, though.
