[NTG-context] Proper kerning of quotations in German

Hello, I already noticed that English quotations are much better kerned than the German (also Slovenian) ones, today I also came across two articles about this. http://www.harald-harders.de/latex/lm-kerning-092.pdf http://www.dante.de/dante/events/eurotex/papers/TUT09.pdf If I understood it properly, the problem should have been addressed and solved already. Is there already any ConTeXt support for it? German/Slovenian/... can use either guillemots or normal quotation marks, so if the user wants to use guillemots (which are not the default), a simple mechanism has to exist, where the kerning is updated automatically when switching.
