Oh my...
I know what's the problem, when you edit your code, a lot of people who use firefox fex see the code with spaces in between, and that does in fact screw up code that uses $&.
It never looks like it has spaces in between lines for me (what you posted looks exactly like my post for me), but I remember that a lot do see it like that after the author has edited his code. Second time this screws up a snippet of mine.
Damnit.
EDIT: I have checked, it indeed shows the code with spaces in between lines when viewing with firefox, this does not happen with Internet explorer! Grrrrrr.... this is the last time I use code tags, even though they make the code easier to read because of the indent.
