<p>A character must be <code>char-whitespace?</code> if <b>either</b>
it's General Category property is any of:
Zs (Separator, space)
Zl (Separator, line)
<b>or</b> if it is any of the codepoints:
U+0009 (HORIZONTAL TABULATION)
U+000D (CARRIAGE RETURN)
U+000C (FORM FEED)
The name "CARRIAGE RETURN" makes me long for a computer keyboard with
one of those big metal levers found on mechanical typewriters. And a
mechanical bell, too.
