.bind() and .one() don't allow a function as data

[davidflanagan]

The .bind() and .one() methods take two or three arguments, and have the signatures:

bind(type, data, handler) bind(type, handler)

Currently, jQuery 1.4.2 distinguishes these cases with this code:

if ( jQuery.isFunction( data ) ) {

fn = data; data = undefined;

}

This means that if you pass a function as the data argument, it will be treated as the handler argument and the handler will be ignored.

I propose that you change the code to instead test like this:

if (arguments.length === 2) {

fn = data; data = undefined;

}

See line 2371 in jquery-1.4.2.js for the code referred to above. (It doesn't look right the way I pasted it into the ticket.)

Retarget all enhancements/features to next major version.

Allow function to be passed in as a data object to bind and one. Fixes #6993.
