    eval: Use the correct expansion mode for fd redirection

    It has been reported that

            echo test >&$EMPTY_VARIABLE

    causes dash to segfault.  This is a symptom of the bigger problem
    that dash tries to perform pathname expansion as well as field
    splitting on the word after >& and <&.  This is wrong and this
    patch fixes it to use the same expansions as done on a normal
    redirection.
