Log message:
Changed the behavior of the dT and eqcdT tactics on goals with
conclusions of the form
<< (quot x1, y1: 'A1 // 'E1['x; 'y]) =
(quot x2, y2: 'A2 // 'E2['x1; 'x2]) in univ[@i:l] >>
(to use the quotientWeakEquality rule instead of the quotientEquality
rule). The old behavior is recovered with altT.
I would be very surprised if this broke any proofs; the original
tactic created subgoals of the same form as the current goal, and I
don't think there's any way to prove those subgoals.
