Change in Times[] behavior from Mathematica 7 to Mathematica 8

While testing Mathematica 8 on some heritage code, I found a problem
which a colleague traced to a behavioral change in Times[].
Specifically, the documentation for Times[] states that "0 x evaluates
to 0, but 0.0 x is left unchanged."  This appears to be true in
Mathematica 7 but not in Mathematica 8 (at least not under Mac OS X
10.6.4).

I have informed Wolfram about this change (bug?).
