On the languagechooser/language-name: i found this question is better
displayed using a Tree rather that a List of items: i've created an
ad-hoc question handler, only for that particular question, that
represents continents as father iterators and Nation names as Children
(soon on SVN).
Fathers items are individuated because they begin by "--" and end with
"--" (e.g.: "-- Europe --" ): are there others questions in the d-i that
would benefit of such a representation (i'm thinking about the main
question in the partiotioning tool) ?
Are you *really* talking about languagechooser/language-name here ?
Continents grouping is for countries, so for the countrychooser part
of localechooser, not the languagechooser part.
