I'm in a similar situation where I don't want any filetype plugin to
set the 'o' in 'format options:
autocmd FileType * setlocal formatoptions-=o
I put this in my vimrc _after_
filetype plugin indent on
so that it is executed after all the filetype plugins.
You could something like this (untested):
set tw=80
autocmd FileType * if &l:tw != 0 | setl tw=80 | endif
I don't think you need to care that this is not executed for buffers
with no file type because no filetype plugins will be sourced for
them, either.
