mbrtoc32: document (size_t) -3 issue
Portability problems not fixed by Gnulib:
@itemize
@item
+This function behaves incorrectly when converting precomposed characters
+from the BIG5-HKSCS encoding:
+@c https://sourceware.org/bugzilla/show_bug.cgi?id=30611
+glibc 2.36.
+@item
Although ISO C says this function can return @code{(size_t) -3},
no known implementation behaves that way,
and if it were to happen it would break common uses.
