Here is a patch to gnus-gl.el that adds another user-format function
that doesn't rely on having the Grouplens info plugged into the Gnus
scoring mechanism.  This allows both "normal" SCORE/ADAPT scoring and
Grouplens predictions to be displayed in the summary line.  No changes
to existing code were needed.

I am also including the relevant section of my Gnus rc file so you can
see how I set up to use this function.  Groups that are handled by the
BBB have the prediction shown.  Groups that aren't show my "normal"
summary line.
