In function ' split_pathtarget_at_srfs ', we invoke ' add_new_columns_to_pathtarget ' to
add expressions to pathtarget, but do not set sortgrouprefs of pathtarget. I think it may be better to
set sortgrouprefs here.

Thanks for the patch! I've been wondering what causes this regression failure, so thanks for investigating. I'll review the patch soon.

Does that mean you think there might be a better way to fix this issue?
