I'm thinking something like this.
The examples for runtime pruning are lame -- in the first, the text says
"watch out for Subplans Removed" and then the example provided doesn't
show one. (That example is probably exercising the wrong thing.)
Anyway, wording suggestions for 5.10.4 and 5.10.5 in the attached file
are welcome.
