[FIX] No touchy.  If it doesn't seem to work, find the underlying cause; don't hack at it until it goes.
admin_bar wasn't setting values, as $feature was a non-null value; but it also wasn't the actual feature value;  so its feature chain was empty; so as far as the part which was loading features was concerned, there were no features [1].
The duplicate setting of values in the main magic file seemed to work; but mostly because it was overwriting the empty values [from 1] with the actual values.

Don't touch this unless you understand the effects of the changes you are making.  It makes me angry when I have to fix things.  It is not good when I am angry.
