regexec: Fix off-by-one bug in weight comparison [BZ #23036]
Each weight is prefixed by its length, and the length does not include itself in the count. This can be seen clearly from the find_idx function in string/strxfrm_l.c, for example. The old code behaved as if the length itself counted, thus comparing an additional byte after the weight, leading to spurious comparison failures and incorrect further partitioning of character equivalence classes.
