ZF-6782: use of Zend_Locale in Zend_Translate
is not equal with
if, let's say, I want to define ONLY 'en' or 'en_US', which, in my opinion, is the same.
To have Zend_Translate understand both locales, I have to duplicate the translations for both locales. This is not an option in case of large translations files on large projects.
Suggestion: use only the language part of the locale or, even better, if the locale have an exact match in the translation arrays use it, else use only the language part of locale.
