Extraneous comma

Chapter 9: Lambda expressions and expression trees: P233, first text line

On page 233, in the first line of normal text, there's an extra comma in the quoted output. So where it says:

Listing 9.1 prints "5," just as we'd expect it to.

It should instead read:

Listing 9.1 prints "5" just as we'd expect it to.

The same issue comes up elsewhere in the text - we should probably use an automated "find" to check for all potential candidates.
