babelCall strange logic

[Jean-Marc Lasgouttes]

Currently, BufferParams::babelCall reads like:

string const BufferParams::babelCall(string const & lang_opts) const
{
        string tmp = lyxrc.language_package;
        if (!lyxrc.language_global_options && tmp == "\\usepackage{babel}")
                tmp = string("\\usepackage[") + lang_opts + "]{babel}";
        // suppress the babel call when there is no babel language defined
        // in the lib/languages file
        if (lyxrc.language_global_options && tmp == "\\usepackage{babel}" &&
                language->babel().empty() ) {
                // if the armscii8 or a CJK encoding is used, babel has to be 
called
                // for foreign languages
                if (!lang_opts.empty())
                        tmp = string("\\usepackage[") + lang_opts + "]{babel}";
                else
                        tmp.clear();
        }
        return tmp;
}


Uwe, I do not understand why lang_opts is passed to babel in the
second if() when lyxrc.language_global_options is true. What was your
intention?
