[Patch] Validator should not complain about reg_name without name

[GerdP]

What steps will reproduce the problem?

1. Create way with tag reg_name=Hansalinie and maybe highway=motorway
2. Run validator

What is the expected result?

no warning

What happens instead?

warning "alternative name without name"

Please provide any additional information below. Attach a screenshot if possible.

I am not sure if this tag is correct, it is used for many members of relation 5611236. I remember that the road was called Hansalinie when I was young, but I did not here that name for a long time.
Attached patch changes the rule to treat reg_name like old_name.

One more thought: Maybe the test would perform faster if the exceptions where added to the regex instead? I am sure that is possible but I am not very fit with regex syntax.

Isn't Hansalinie a name, like in ​https://www.openstreetmap.org/way/381210437 ?
Or the name is Bundesautobahn 1 with reg_name = Hansalinie? ​https://de.wikipedia.org/wiki/Bundesautobahn_1

No idea, I always call it by its ref: A 1. Maybe something I should ask in the German forum first?
