Not according to my testing [1]. I'm seeing three different behaviors from
Safari 6.0, Opera 12.0, and FF 14.0.1 (current downloads). This seems
pretty inconsistent, and indicates to me that Web authors are effectively
ignoring these differences (by using their own normalization). Given this
case, I think we have some leeway to choose which version we think is most
correct.

Safari - appends "; " [SEMICOLON SPACE]
Opera - appends neither ";" nor "; "
FF - appends ";" [SEMICOLON]

I haven't tested a recent version of IE.
