While I've managed to work out the difference between :blank: and :space: by looking at the source code (:blank: matches [ \t], while :space: matches [ \f\n\r\t\v] and possibly other characters depending upon the locale), I have trouble accepting that this difference is obvious from the names. Could you add some text explaining this difference? Colin Percival
