Yes, I agree.  Maybe we can add a `prog-prettify-uninstall' function
that expects the buffer-local `prog-prettify-symbols-alist' to be
unchanged and removes all compositions named in it?  And that can be
added to the font-lock unload hook when `prog-mode' is installed?

Or should it be lower level, where font-lock mode remembers "prettify"
compositions as a text property?  That would work regardless of
`prog-prettify-symbols-alist' and would not require an unload hook.  It
would also work if we add prettification in other modes, not just
`prog-mode'.
