On system with signed char, ascii would incorrectly handle bytes with the
highest bit set.
Before:
$ ascii $(printf '\xff')
ASCII 268435455/15 is decimal 4294967295, hex ffffffff, octal 37777777777,
bits 11111111: meta-^_
After:
$ ascii $(printf '\xff')
ASCII 15/15 is decimal 255, hex ff, octal 377, bits 11111111: meta-^?
