uppercasing in Germany: Au, dashes

HI,i,

I have the strong suspicion that for Germany the word "Au" is treated as a binding/grammar word. For example. 'an', 'am' translate to something like 'nearby'. 'Au' on the other hand is an old word for a field next to a river. Especially in Southern Germany and Austria "Au" by itself is the name of villages or cities.
There are lots of places called "Au" in the data and those are fine http://woe.spum.org//search/Au?placetype=town&page=2

But as soon as "Au" is not the first word I see it lowercased. Examples:
Todtmoos-au http://woe.spum.org/id/699604
Gemeinde au am Rhein http://woe.spum.org/id/12623899
Gemeinde au in der Hallertau http://woe.spum.org//search/au%20in%20der%20Hallertau

In those examples "Au" should be uppercase.


Somewhat related: Again in Germany for localAdmin types, whenever I see a dash both words before and after are cities. So both should be uppercase. Examples

Quite specific feedback, but I rather share it than adding fixes on my end only.
