[jQuery] typo in docs for "post" entry

Hey, I couldn't tell if this should get posted here or in Trac, so I'm
posting it here.
I wanted to point out a bug in the docs:
http://docs.jquery.com/Post
function(returned_data)
{
alert(data);
});
should be:
function(returned_data)
{
alert(returned_data);
});
