The latter. But the fix I made to the Lisp has nothing to do with Emacs 20
per se. Without your C change, it's also needed for Emacs 22. If your C
change ensures that everything written is readable, then reading is not
needed in Lisp, of course. I wasn't clear on your C change, and I thought
you had just forgotten the read that was there before (for Emacs 22). Sorry
about that.

The Emacs 20 bug only served to help me test. Otherwise, it's irrelevant
here.
