Set commentstring for files of unknown extension

Question

I want to find a way to set my default commentstring to '#' for files of unknown extension. As far as I know, there is no way to do this.

Issuing a setlocal commentstring=#\ %s on my .vimrc would overwrite the commentstring of all known files.

So, I came up to the following solution that works great :

autocmd BufNewFile,BufRead * if &syntax == '' | setlocal commentstring=#\ %s | endif

Idea taken from here:

vim default syntax for files with no extension

True, thanks for that. Edited to add it. I am not sure why I am being downvoted ? Anyone care to explain it to me ?

Because your Q and A are the same text, so it is not really correct site usage. You post a question in the question, and answers in answers. They dont really mix (it’s not a forum where text can just go everywhere).
