SPUG: regular expressions

Bear with me for a newbie question, I'm right at the second regex 
chapeter in Learning Pearl and this question caught my attention:

What does the (\w) in the pattern do to the \b word separator? I thought 
it might give whitespace as the word delimiter (and so keep words like 
"that's" as a single word) but the output still comes out as "That'S."

How else could I treat contractions?
