Before that, Split("abcd",";","\\;") did nothing useful, as an escape 
character cannot be a splitting character. No error was raised in that 
case, you just got some undefined behaviour.

So I decided to use that syntax to implement a different way of 
splitting the string. Instead of escaping with enclosing characters 
(everything between these two characters cannot be split), I escape 
characters one by one with the special character indicated in the 
beginning of the escape string.
