2563 (path::_List::_Impl::_M_erase_from(const_iterator)): Define.
2564 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
2566 (path::_List::pop_back()): Define.
2567 (path::_List::_M_erase_from(const_iterator)): Define.
2568 (path::operator/=(const path&)): Use pop_back to remove last component
2569 and _M_erase_from to remove multiple components.
2570 (path::_M_append(basic_string_view<value_type>)): Likewise.
2571 (path::operator+=(const path&)): Likewise.
2572 (path::_M_concat(basic_string_view<value_type>)): Likewise.
2573 (path::remove_filename()): Likewise.
2574 (path::lexically_normal()): Use _List::_Impl iterators instead of
2575 path::iterator. Use pop_back to remove components from the end. Clear
2576 trailing filename, instead of using erase(const_iterator) to remove
2577 a non-final component.
