The documentation is incorrect due to a copy/paste mistake. I am the person who implemented "set -show". It is a debug tool. It is not meant to be used in the same way "set -q" is meant to be used. Restricting the scope would defeat the purpose of "set --show" as the intent is to help people understand why, for example, the uvar value isn't being used because it has been shadowed by a global or local scope.
