Description
$("body").is("div span") is returning true
it should always return false, since a body element is /not/ a span element which is a descendant of a div element.
is() seems to return true if there are any two things separated by space, for instance $(whatever).is(".bigclass .otherclass")

can you at least mention that in the documentation? it only says it supports "expressions", which anyone would logically assume means anything on the "selectors" page of the docs.

'''Note:''' Only simple expressions are supported. Complex expressions, such as those containing hierarchy selectors (such as +, ~, and >) will always return 'true'.
Please follow the bug reporting guidlines and use jsFiddle when providing test cases and demonstrations instead of pasting the code in the ticket.
Note: See

tickets.
is() doesn't support complex selectors (those including spaces, >, etc). We might add this for 1.3.
