* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.

Without this fix, on a 64-bit host (aset S 0 4294967386) would
incorrectly succeed when S was a string, because 4294967386 was
truncated before it was used.

         * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
         Otherwise, an out-of-range integer could cause undefined behavior
         on a 64-bit host.
