This seems wrong to me in two respects.  It doesn't do anything to NUL,
which was the original problem character; instead, it marks as punctuation
^I (TAB), ^J (LFD), ^L (FFD), and ^M (CR), which should probably be left
as whitespace.  One could also make a case that such characters as ^?
(VTB) should remain whitespace, although I've never seen anyone use that
one.
