if PYTHONUNBUFFERED=x ksvalidator my.ks | grep '.'; then false; fi

[Marc Herbert]

Hi,

 I was glad I just discovered "ksvalidator", implementing a useful
feature. I was less happy about how painful it was to script it
(see workarounds in email subject). Shouldn't these exit status and
buffering problems be at least flagged in the usage message?

Cheers,

Marc
