Well, I fixed it myself, basically. Those wire looped things up inside the housing pull down, but I couldn't get them to attach to the rim for nothin'.
Dunno if they were sprung or I'm just stupid or some of both.
It's a pretty old fixture...
So, twist tie technology to the rescue!
I attached a twistie, snugly, one to each side, at the bottom where the loop is and through a slot on the inside edge of the rim thingie, and then slid it up and voila! Let there be light!
And it should be safe 'cause the twisties aren't touching the light bulb. They are separated by the tube of housing around it.
Phew, are my arms tired--ceiling lights are tough!
I have a new appreciation for electricians!
