There are a bunch of other potential gotchas with (z) from that
standpoint, such as special treatment of redirection operators.  If
what you really want is purely quotation parsing, it may be better to
add something new rather than modify (z).

Also it is helpful to have something that can distinguish a newline
that would be parsed as a command separator from one that
shell-syntactically is merely whitespace.  That was Felix's original
problem all those years ago.
