The check for shell special characters, which results in single quoting,

In fairness, I don't think it's strictly incorrect to say that the outcome
is different "for" one of two commands used in a trivial example. I was
only attempting to clarify the circumstances that begat the original question.
I understand. The point is that it's faulty reasoning to say that it's a
difference between two commands when there are more differences than the
(builtin) command name itself. It's one of the first rules of
troubleshooting: reduce the number of variables between cases.
In this case, running `:' and `unset' with the same arguments would have
shown that that difference was in how the arguments are treated, not the
builtin itself.
