Potential typo in Table 4.1: Pattern-matching cases

[stephenscliu]

For the fourth row in Table 4.1: Pattern-matching cases, my impression is that it's trying to match the * pattern against the empty string. Right now, the text is a closing double quote followed by an opening double quote (rather than opening then closing), which I feel like might be a typo.

thanks for the report - that's weird, but I should be able to fix it.
