Subject: [PATCH] [regexp] Document incorrect assertion in
 intl/regress-10573.js
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are at least three equivalence classes where this assertion
should not actually hold:

  '\u0390\u1fd3',              // ΐΐ
  '\u03b0\u1fe3',              // ΰΰ
  '\ufb05\ufb06',              // ſtst
