custom filters don't work in $.sub()

[james@…]

1. create a $.sub()
2. add methods to the sub's expr.filters or expr:?
3. try to use those filters
4. "Syntax error, unrecognized expression"

I'll take a look at this

Our medium-term goal is to move jQuery.sub() into a plugin so I don't think we'll be enhancing it.
