What is the problem with this particular part? What shell are you using
that doesn't understand $() command expansion? Even the basic BSD "sh"
does support this. However this doesn't really affect anything, and
should work in all shells too.

This looks reasonable to me. Wine uses match() to find a matching ">" so
 index() would do just fine.
