A negative look-behind would be the perfect, simple approach to this  
regex problem. Unfortunately, Ruby's current regexp handler does not  
have such a feature. Fortunately, the regexp handler of the next  
version of Ruby does. Even more fortunately, this future handler  
(Oniguruma) is available now.

So, you can write a more complex regexp/logic to detect your current  
case, or you can get Oniguruma working and use a negative look-behind.
