I should note that it's possible that this introduces memory leaks for
global-scope parameters, because it introduces a case where a struct
param with the PM_UNSET flag remains in the global parameter table.
Ordinarily that only happens to function scope parameters.  I think
such leaks, if they exist at all, would be detectable only when the
shell is about to exit anyway.
