4288 * include/bits/fs_path.h (path::_List::erase): Replace both overloads
4290 (path::pop_back(), path::_M_erase_from(const_iterator)): New member
4291 functions that will only erase elements at the end.
4292 * src/filesystem/std-path.cc (path::_List::_Impl::pop_back()): Define.
4293 (path::_List::_Impl::_M_erase_from(const_iterator)): Define.
4294 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
4296 (path::_List::pop_back()): Define.
4297 (path::_List::_M_erase_from(const_iterator)): Define.
4298 (path::operator/=(const path&)): Use pop_back to remove last component
4299 and _M_erase_from to remove multiple components.
4300 (path::_M_append(basic_string_view<value_type>)): Likewise.
4301 (path::operator+=(const path&)): Likewise.
4302 (path::_M_concat(basic_string_view<value_type>)): Likewise.
4303 (path::remove_filename()): Likewise.
4304 (path::lexically_normal()): Use _List::_Impl iterators instead of
4305 path::iterator. Use pop_back to remove components from the end. Clear
4306 trailing filename, instead of using erase(const_iterator) to remove
4307 a non-final component.
