AFAIU, `user-error' is to be used when, according to its docstring:

    This is like ‘error’ except that a user error (or "pilot error") comes
    from an incorrect manipulation by the user, not from an actual problem.

So if that is the case here, then it should be `user-error's and
otherwise it should be plain `error's.  Right?
