Hi, all,

I'm looking for a kind soul to check the fix for #10741, which deals with 
left/right matrix actions on binary quadratic forms (in BinaryQF).  The code, 
as it is now, does not produce an associative action, i.e.,
  Q.matrix_action_right(M).matrix_action_right(N) !=
        Q.matrix_action_right(M*N)
and similarly for the left action.

The fix is simple (just swap the choice of matrix elements used in each case: 
columns for right action, rows for left).

I'm willing to condone a modest level of bribery :-}

Justin
