[Plone-i18n] New Plone 4 site creation and cs-CZ language code

[Radim N. <nov...@gm...>]

Hi,

I'm testing Plone 4 and realized my native language is not selected by 
default on the site creation page (@@plone-addsite).

If this page is accessed from Safari, preferred language is cs-cz
 >>> IUserPreferredLanguages(self.request).getPreferredLanguages()
['cs-cz']

If this page is accessed from Firefox, preferred language is cs and 
everything works fine.
 >>> IUserPreferredLanguages(self.request).getPreferredLanguages()
['cs', 'en']

'cs' is language code, 'cz' is country code.

Is 'cs-cz' combination missing in plone.i18n.locales/languages.py, 
_combinedlanguagelist ?
