Okay, but there is a whole upgrade mechanism in place that's
specifically for upgrading the .newsrc.eld file to a new version, so
this wouldn't be the first time it's happened.

That said, the current situation seems to be working fine; if we've got
to keep it, we've got to keep it. I'd like to keep this bug report open,
though.
