Another is to mount the supplemental Cutler Hammer ground bus bar
in the case, feed it with a large diameter wire from the existing neutral
bus bar and move the three or four ground wires now connected to the bus
(old house, very few grounded outlets) to the supplemental ground bus bar.

Why wouldn't you do it this way? this seems to be the easiest/safest
solution, short of full panel replacement.

The third seems to be what most people do. Put two wires under a setscrew
and print up a big label for the box "Disconnect Main Breaker Before Neutral
Rewiring!"

I really don't like this idea, for reasons already discussed.
