Better TeXization?

[Ilya Zakharevich <ilya@math.ohio-state.edu>]

? \o2
   output = 2 (prettyprint)
? default(seriesprecision,5)
   seriesprecision = 5 significant terms
? sin(x)*sin(y)
          1 3    5     -1    1  3    5   3    5
%2 = (y - -y +O(y ))x+(--y + --y +O(y ))x +O(x )
          6            6     36

Would not it be nicer if O(y^5) is left as is, but the other parens
\left\right-ized?
