	/**
	 * This function is a wrapper of dgettext() which does not translate
	 * the message if the default domain as set with textdomain() has no
	 * translations for the current locale.
	 *
	 * The advantage of using this function over dgettext() proper is that
	 * libraries using this function (like GTK+) will not use translations
	 * if the application using the library does not have translations for
	 * the current locale.  This results in a consistent English-only
	 * interface instead of one having partial translations.  For this
	 * feature to work, the call to textdomain() and setlocale() should
	 * precede any g_dgettext() invocations.  For GTK+, it means calling
	 * textdomain() before gtk_init or its variants.
	 *
	 * This function disables translations if and only if upon its first
	 * call all the following conditions hold:
	 *
	 * - @domain is not %NULL
	 *
	 * - textdomain() has been called to set a default text domain
	 *
	 * - there is no translations available for the default text domain
	 * and the current locale
	 *
	 * - current locale is not "C" or any English locales (those
	 * starting with "en_")
	 *
	 * Note that this behavior may not be desired for example if an application
	 * has its untranslated messages in a language other than English. In those
	 * cases the application should call textdomain() after initializing GTK+.
	 *
	 * Applications should normally not use this function directly,
	 * but use the _() macro for translations.
	 *
	 * Params:
	 *     domain = the translation domain to use, or %NULL to use
	 *         the domain set with textdomain()
	 *     msgid = message to translate
	 *
