Why remove this?

[Julius, 2015/07/07 01:14:21]

Because now language_code can actually be empty if the user unselects all
languages.

   const std::string action = base::StringPrintf(
       "LanguageOptions_SpellCheckLanguageChange_%s", language_code.c_str());
   content::RecordComputedAction(action);
