If the standard does intend this to be the case, then we don't need to

Absolutely you can use the array form. Anybody who suggested that
anything should work right when widen gives different results for
single char and array forms would be laughed off the list.


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!
