Description
This may seem a little bit odd to be searching for an id-less element, but i found a few places in existing code that were in loops and the id variable had no value. Previos versions returned a jQuery object with a length of zero, but from 1.3.1 an exception is thrown.
[Exception... "'Syntax error, unrecognized expression: #' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "<unknown>" data: no]

I modified the ID and Class regexes to use '*', instead of '+' and it didn't break any tests in FF 3.0.7.
It's questionable whether this is the desired behavior, though. I don't think this approach would make sense when applied to attributes that aren't unique (should $('.') yield no elements, or all elements with no classes?).
