this is something that bothers me since 3.0, so yeah, very old!
At functions_content we've this line:
`$message_parser->message = $quote_attributes['author'] . " " . $language->lang('WROTE') . ":\n" . $message . "\n";`
In my language I don't want to have "Author Wrote:" but instead "Wrote by Author"
So I beleive this could be enhance to give the power to the translation file and not be hardcoded like that.
