Try the attached solution. I took the regular expression parser and
adapted it to use the base iterator for position_iterators. It's a bit
of a hack so it probably shouldn't be added to spirit. And I haven't
tested it much.

Other solutions would be to write a bidirectional position iterator or
just manually work out the positions after parsing. Or maybe track the
position in the lexer, but I think that'd be hard with spirit.
