.removeClass() doesn't work without parameters

[MichaelM]

removeClass without parameters still passes an argument length of 1, so

proceed = arguments.length === 0 || typeof value === "string" && value;

should be

proceed = arguments.length === 1 || typeof value === "string" && value;

We'll need proof of that, please provide a test case on jsfiddle.net.

I realized this issue doesn't occur unless jQuery UI 1.9.2 is also being used, my apologies.

I'm going to go open a ticket on their site, but here's the jsFiddle for anyone interested: ​http://jsfiddle.net/nbyCC/3/
