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.
