unilbrk/u*-possible-linebreaks: Fix undefined behaviour. Reported by Jeffrey Walton <noloader@gmail.com>. * lib/unilbrk/u8-possible-linebreaks.c (u8_possible_linebreaks): Don't invoke memset with a zero size. * lib/unilbrk/u16-possible-linebreaks.c (u16_possible_linebreaks): Likewise. * lib/unilbrk/u32-possible-linebreaks.c (u32_possible_linebreaks): Adjust accordingly.
