FunctionExpand bug. Serious.

Hi Group,

I posted a bug notice and someone was kind enough to point
out an error in my polynomial example. The bug appears in
using FunctionExpand on

p[x] = x^6-x^4+2x^2-10

that is,

FunctionExpand[ UnitStep[p[x]] ]

returns 0 when it should return a sum of 2 two UnitSteps.
