-// 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
