shwordsplit does this.  (I thought it would be shglob, but it isn't.)

By the way, I was too glib before: if you have a string that *starts*
with "(", it *does* get split as a complete command line that starts
with a subshell, even in native mode, as you might expect.  So I think
(z) is behaving basically rationally, but with the caveat I mentioned
that it's a fairly brutal tool in comparison with real context
sensitivity.
