There are existing tests that specifically check for the current
behavior, so it's not as if this were simply overlooked.

To write the proposed new test cases, we need to decide (this list may
not be all-inclusive):

whether this is going to be attached to an option (and which one, now
that Oliver to at least some extent disagrees with KSH_TYPESET) or is
controlled by emulation mode;

what happens to "setopt NO_UNSET";

what "typeset -p" outputs following "unset".;

what happens when each (any) of the EFHLRTZilu options are passed to typeset;

whether we are OK with the implications of the foregoing when the -x
option is also present.
