 Cite documentation please and explain where I got it wrong.

 The point was to match one or the other as this was something that
 someone else wrote that's a valid regular expression in bracket
 notation that I executed on both FreeBSD and Linux. '\040' != '\011'
 and as such a space shouldn't be a drop in replacement for a
 horizontal tab. The PR was filed to note the discrepancy.
