Reformatting Question (build 3415)

What setting under "Global Code Style" would cause this code:
public class Test {
int x, y, z;
}
to be reformatted to this:
public class Test {
int x
,
y
,
z;
}
when I select "Code-->Reformat Code..." ?

I'm not sure if it's a setting I've changed, or if it started happening somewhere along the way in the EAP builds. It can be very frustrating when you have a long list of variables that you have to fix after reformatting.

Thanks,
Kris
