I don't follow: have you seen libstdc++/12988? Whatever we do as regards
cache management, if we don't use in any case the single char form, how we
can imagine fixing the bug? A user cannot be forced to always override both
forms in the same way and 22.2.2.2.2, p14 is clear about which form must be
called!
