I ended up having to do it in a kind of ugly way to get a file that
libexpat would parse and Emacs would still recognize as read-only.

This version libexpat failed to parse:

<!-- THIS FILE IS GENERATED -*- buffer-read-only: t -*-  -->
<!-- vi:set ro: -->
<?xml version="1.0"?>

This version Emacs didn't mark read-only:

<?xml version="1.0"?>
<!-- THIS FILE IS GENERATED -*- buffer-read-only: t -*-  -->
<!-- vi:set ro: -->

So I'm using this:

<?xml version="1.0"?> <!-- THIS FILE IS GENERATED -*- buffer-read-only: t -*-  -->
<!-- vi:set ro: -->

I haven't tested in vim though.

Oops, I just copied the license block from update-gnulib.sh I think.  Fixed.
