This would be a real pain. What if the string being displayed is a
display property on the before-string? You have to not just check all
3 of before-string, display, and after-string overlay properties, but
you also have to scan through both the before-string and after-string
properties looking for display text properties.
(By the way, in a separate message, I have complained about a bug that
strikes when eq strings are used in distinct display properties.)

I don't think it is good enough even for experimenting, for the reason
I indicate above.
