    This would be a real pain.  What if the string being displayed is a
    display property on the before-string?

The experiments don't need to handle such complex cases
in order to serve their purpose: to figure out the right
criteria for which overlays' properties should influence
which overlays' strings.

Once we are confident of the right criteria, we could
implement them cleanly and reliably and efficiently.
