+       unistr/u8-chr, unistr/u8-strchr: Optimize and add comments.
+       * lib/unistr/u8-chr.c (u8_chr): Add comments. Remove a useless test at
+       the beginning of the loop.
+       * lib/unistr/u8-strchr.c (u8_strchr): Add comments. Don't fall through
+       cases in 'switch' statement.
+
        unistr/u8-strchr: Fix several bugs.
        * lib/unistr/u8-strchr.c (u8_strchr): Don't search beyond the end of
        the string. When not found, return NULL, not a pointer near the end.
