1848 with ...
1849 (path::pop_back(), path::_M_erase_from(const_iterator)): New member
1850 functions that will only erase elements at the end.

1853 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
1854 of erase(p, end()).

1856 (path::_List::_M_erase_from(const_iterator)): Define.
1857 (path::operator/=(const path&)): Use pop_back to remove last component
1858 and _M_erase_from to remove multiple components.
1859 (path::_M_append(basic_string_view<value_type>)): Likewise.
1860 (path::operator+=(const path&)): Likewise.
1861 (path::_M_concat(basic_string_view<value_type>)): Likewise.
1862 (path::remove_filename()): Likewise.
1863 (path::lexically_normal()): Use _List::_Impl iterators instead of
1864 path::iterator. Use pop_back to remove components from the end. Clear
1865 trailing filename, instead of using erase(const_iterator) to remove
1866 a non-final component.
