+Fix :meth:`datetime.datetime.strptime`, :meth:`datetime.date.strptime` as
+well as :func:`time.strptime` (by modifying :class:`_strptime.TimeRE`) to
+make ``%c`` and ``%x`` accept year number representations consisting of
+fewer digits than the usual four or two. Thanks to that, certain
+``strftime/strptime`` round trips (such as
+``datetime.strptime(dt.strftime("%c"), "%c"))`` for ``dt.year`` less than
+1000) no longer raise ``ValueError`` for some locales/platforms (this was
+the case, e.g., on Linux -- for various locales, including
+``C``/``C.UTF-8``).
