filter() should accept the same arguments as not()

[joern]

Assuming that the variable selector in the following example can be a selector string and a DOM element or jQuery object:

headers.not(headers.not(selector))

This should be the same as:

headers.filter(selector)

but filter accepts only callbacks and strings.

Why? What would be the purpose of passing in either one of those? In both cases it would just reduce the jQuery object to nothing but what you passed in - effectively making it the same as $(element

object).

An example:

headers = $("div.header");

// some client code passing in the selector
selector = ":eq(0)"
// works, because filter accepts strings
headers.filter(selector) 

// same client code, but passes in an dom element
selector = document;
// doesn't work
headers.filter(document)
// works
headers.not(headers.not(selector))
