[Talk-GB] C roads

[Ed Avis]

In general it would be good to distinguish between what is signed and what is
known to be true, though it may not be signed.  Ultimately, road signs and street
nameplates could be mapped as separate objects, though that might be going a bit
far.

In country areas there are many road names known to locals but not signed at all.
A navigation app might not bother to say 'turn left down Lewsley Lane' if it
knows that there is no marker on the ground to help a driver find it.  But then,
it would still be useful to show the name in local maps or tourist guides.  In
cities, if a street has no name sign anywhere I will tag unsigned=yes.  In the
countryside, having no sign is the common case so I don't usually add the tag.

Similarly there are old hotels which still have the name carved in stone above
the doorway but are nowadays used for something else.  Nobody would put that into
the name tag but it might possibly be useful for 'name_sign' or 'signed:name' or
various increasingly complex tag schemes.
