For pickups which have a separate non-signal-carrying shield braid (hint, there must be at least two wires besides the braid), move the negative lead to the signal return ring but leave the non-signal-carrying shield soldered to the pot shell or other shield-ground point.
After contacting GFS about my lil killer pups (and getting a very prompt response via email) Jay says:
The black wire is ground for the coils- the Silver wire is ground for the baseplate- You CAN leave the silver ungrounded- and on some guitars that is preferable.
So do I assume that the silver braid baseplate wire can be either taped off or soldered to a pot shell and not go to signal return?
sounds good to me. of course, if you leave it ungrounded, you don't get any shielding benefit from it. On the other hand, if it's soldered to the back of a pot, it does eventually meet the signal return anyway.
the three l'il killers on my qtb'd strat actually have the p-up shield taped off, and it's amazingly quiet.

That's why I asked this question. I have the shield braid and the negative lead tinned together from a previous install and wondered if it would make any difference if those two went to the star ground or not. It seems to me that everything eventually gets to signal return anyhow unless you tape off the braid. But that's why I am on this forum because I am no expert.
Well, the shield braid could be connected to a metal part of the pickup that you might touch while playing. If there is a problem with the amp you plug into, there could be high voltage on the signal ground (actually, i think, between the hot and signal return). The shield braid is connected to the back of the pots and the bridge ground and then isolated from the signal return via a capacitor in order to keep those parts you might touch from killing you. Shouldn't make a difference in the sound.
