[Tagging] Sample tagging for highways with no lane markings

I agree with the solution mentioned by Thorsten. The keys oneway=no +
[lanes=2] + division=no have much more sense to me than tagging lanes=1 +
oneway=no for this kind of highway (just the same width that a two lanes
way but without division).

A proper value could serve to indicate also that the division was present
once ago but actually are blured, as Martin suggested.

I would like a proposal for the division key and a clarification in they
key lanes wiki.

Cheers, Javier
