The regular expression previously used here to select the second comma-delimited argument won't work when we introduce an argument containing a comma, which I need to do now. We can address this by recognising Autoconf's quoting mechanism (which uses square brackets). This is not 100% right (it doesn't understand nested square brackets), but it's good enough in practice.
