 // This function takes a GURL object and elides it. It returns a string
 // which composed of parts from subdomain, domain, path, filename and query.
 // A "..." is added automatically at the end if the elided string is bigger
 // than the available pixel width. For available pixel width = 0, empty
 // string is returned. |languages| is a comma separted list of ISO 639
 // language codes and is used to determine what characters are understood
 // by a user. It should come from |prefs::kAcceptLanguages|.
 //
 // Note: in RTL locales, if the URL returned by this function is going to be
 // displayed in the UI, then it is likely that the string needs to be marked
 // as an LTR string (using base::i18n::WrapStringWithLTRFormatting()) so that it
 // is displayed properly in an RTL context. Please refer to
 // http://crbug.com/6487 for more information.
