J. Nick Koston 2852d86a2f Address review: robust regex and comment accuracy
- Fix extract_packed_value regex to handle commas in entity names
  by matching C++ string literals instead of [^,]+
- Only describe dc/uom/icon in comments when their index is actually
  non-zero, so comment matches what was packed
