Sorry. Should have trimmed more of the original. Nothing to do with
makefiles. I was just providing an example where '| col -b' didn't seem
to filter out any color sequences at all, as far as I can tell. But it
would be nice to know whether I'm using it incorrectly, or whether Ben F
found 'col -b' useful for filtering some other kind of 'color'.
