AFAICT, the only difference between quotewords and split is that
quotewords takes into account quotes to allow "multiple words" to be
parsed as a single token. I don't think we have use for such a feature
(there are no such files in the archive).

So, unless I'm missing something, this could be further simplified to
just use split.
