OK, added.  The tests still pass (both interactively and in batch mode).

The first one, when I evaluate it, makes Emacs segfault.  Not sure why
it works when I'm running the tests - I'd guess because Emacs is not
trying to display it?  Let me know if you want a backtrace for this
crash and/or a separate bug report.

In any case, I've attached an updated patch with the two above
snippets included in the save/load test.  Not sure if we should keep
the first one around, but I added a warning not to evaluate it.

What do you think?

Thanks,
Stefan Kangas
