> Consider the following regular expression:
> "(ab) | (a)"
> with the following input string:
> "abracadabra"
> If you use an instance the RegularExpression class to replace any matching 
> substrings with the empty string, the result should be the following string:
> "rcdr"
> Instead, just the last "a" in the string is replaced:
> "abracadabr"
> If you use the same RegularExpression instance to tokenize the expression, 
> the result should be the following set of strings:
> ""
> "r"
> "c"
> "d"
> "r"
> ""
> Instead, the result is
> "abracadabr"
> ""
> I will attach a proposed patch, but I don't know this code well, so it would 
> be great if someone could review it.
