    Improve semantics of wild-card expansion (fixes #5334) · 5d89565b

    When expanding the {..} stuff in an *expression*, take
    account of which variables are in scope.
    I updated the documentation, and in doing so found that
    part of the previously-documented semantics wasn't implemented
    (namely the stuff about fields in scope), so I fixed that too.
