[Talk-ca] Ref tags in Ontario -- also Manitoba and Quebec

[Pierre Béland]

J'ai commenté il y a 4 mois le changeset suivant http://www.openstreetmap.org/changeset/29085742 invitant le contributeur OntarioEditor a venir discuter. 

Pour les routes du Québec, ces préfixes sont effectivement inutiles avec la classification existante des routes. Ces préfixes n'existent pas sur les panneaux routiers.
Je vais donc utiliser Overpass pour repérer toutes les routes du Québec avec ces préfixe et enlever les préfixes.

It's worth mentioning that prefixes have been added in other provinces as well:
- R (for Route) and A (for Autoroute) in Quebec (e.g. A 40, R 148)- PTH (Provincial Trunk Highway), PR (Provincial Route, i.e. secondary road) and Route in Manitoba (e.g. PTH 15, PR 241, Route 90)
Other than "Route" for metro routes in Winnipeg, the highway shields can be determined algorithmically (in Manitoba, anything above 199 is a Provincial Route; in Quebec, everything below 100 and above 399 is an Autoroute); outside of Winnipeg, there is no chance of confusion as to which route marker to use, as there might be in Ontario.
