Fix #463

Browse Source 
Fix outdated code in macex1, such as checking for unquote-splicing,
    which no longer exists. Also fix macex1 for quasiquoted tables and
    structs. macex1 is not the macro expander used by the compiler, so
    these bugs only affected code which called macex manually, such as
    the short-fn macro.
