Ajax submission of JSON datatype fails if any var starts with '?'

[GoogleCodeExporter]

What steps will reproduce the problem?
$.ajax(
{
 url: '/test/',
 type: 'get',
 dataType: 'json',
 data: { myvar: '?test' },
});

What is the expected output? What do you see instead?
Expected to get '&myvar=%3Ftest' server side. Instead JQuery treats the
value as JSONP, turning it into '&myvar=jsonp[13DIGITNUMBER]test'.
Additionally, while it DOES submit the request, the Ajax query will trigger
neither success or error calls.

What version of the product are you using? On what operating system?
JQuery 1.2.1
Tested on Firefox 2.0.0.7, IE6, and IE7.

Please provide any additional information below.
I quick fixed this for myself by simply commenting out the if block
starting at line 2216. I think, but am somewhat unsure if s.dataType should
be checking for 'jsonp' instead of 'json'. :|
