Seems to be that parameter substitution applies shwordsplit before (z)
gets involved, so we have separate calls to bufferwords() for each of
"one", "(two", "three|foo)" and "four".

Directly at command line, gettok() returns "\210two three\216four\212".

Does the below look correct?

Aside:  "emulate sh" does the equivalent of

    setopt shglob noglob nokshglob

In order to make kshglob work, one must

    setopt glob kshglob

Is that correct, or should only kshglob be needed?
