Review: Needs Fixing
item-separator isn't a drop-in replacement for the space separator which was
introduced previously. If item-separator is specified, it is used to separate
*every* *item* in the top-level sequence, not just adjacent strings as the
space character was before. So, for example:
zorba -z item-separator="--" -q '(<hello/>,<world/>,1,2,3)'
