I don't think I agree either.  Once the user starts changing
read-only-mode, I think disabling it when leaving view-mode would be
surprising.

In any case, leaving it as read-only is only a minor annoyance.
Changing it to read-write means the user can suddenly start doing
destructive things in a situation where that might be unexpected.

So I'm not sure we should do anything at all here.
