 // 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, a
 // formatted, but un-elided, string is returned. |languages| is a comma
 // separated 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.
