In ref_remove_duplicates, when we encounter a duplicate and remove it from the list we need to make sure that the prev pointer stays pointing at the last entry and also skip over adding the just freed entry to the string_list. Previously fetch could crash with: *** glibc detected *** git: corrupted double-linked list: ... Also add a test to try and catch problems with duplicate removal in the future.
