edit:

wait, I thought about it for a second and I see what you meant. You're not saying it's wrong, you're saying it's obvious.

I wasn't sure if it was obvious because I wasn't sure if {1,3} was supposed to be {1-3} and there was a mistake in the expression, or if there was some kind of unexpected error in the [a-z0-9%] expression.

Because even in this simple example, there is room for error.
