I see the problem. isprint is currently true for:
isalnum() || ispunc() || isblank()

\t is in isblank(), but it is also a control char. I have to investigate
whether it is better to not include blank (only space), split the define
into two parts are explicitly mask off cntrl. The first should be allowed
by SUS for the POSIX locale, but I have to check it carefully.
