I agree.  This data would be quite useful to routing software,
especially when combined with information about which lanes have which
turn restrictions.

Yes, it's a lot of work, and people routinely ignore it, but that
doesn't make it wrong.  The way I see it, ignoring short lane number
changes is equivalent to ignoring short traffic dividers (e.g.
http://g.co/maps/cqdmf).  I wouldn't blame someone for ignoring it,
but I wouldn't blame someone for including it either.

Nathan, what is one supposed to do if *all* lanes are turning lanes
(e.g. http://g.co/maps/4j2uh)?  Do we tag it lanes=0?
