descriptors refactor: Use range-for and limit scope of seen_multipath

Browse source 
* Range-for avoids ++i/i++ debate and decreases linecount.
* seen_multipath is only used if multipath_segment_index hasn't already been set. Rename it to seen_substitutes to better describe what it does, now that the context implies its involved in multipath.
