isprint(3)

[Matthew Dillon]

: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.

    It seems to me that the most generic solution is to mask off cntrl.
