+	  vars in previous scopes as invisible and unset so they will show
+	  up as unset until that previous scope returns (similar to how	local
+	  variables in the current local scope are handled). localvar_unset
+	  is currently set to 0 with no way for a script to change its value.
+	  Eventually there will be an option to modify it.  From a bug-bash
