Thanks for the patch.  However, it's not trivial, so it would need
copyright assignment.  Furthermore, there are already known issues where
upstream coreutils is lacking multibyte character support, but a
solution has to be both maintainable and no-impact to the single-byte
locale case.

Huh?  There's no need for either __GNU_LIBRARY__ nor for this
declaration; we can rely on gnulib to be providing mbsnrtowcs on all
platforms.

Therefore, this function has no place in fmt.c.
