$.getJSON() - JSONP callback never gets called

Description
with v1.2.3 + Mozilla Firefox 2.0.0.12, this style of crossdomain $.getJSON() doesn't work, since the callback function never gets called:
$.getJSON( 'http://jquery.com/api/', { callback: '?' }, function (){} );
although this style works fine:
$.getJSON( 'http://jquery.com/api/?callback=?', function (){} );
Here's a demo page:
http://iandeth.dyndns.org/mt/ian/archives/jquery-1.2.3-JSONP-bug/
the problem in the source code is with the regexp at line 2559:
jsre = /=\?(&|$)/g
and line 2567:
s.data = jQuery.param(s.data);
and line 2580:
s.data.match(jsre)
where s.data ends up with some url encoded string like 'callback=%3F', which doesn't match the jsre regexp.
the old version (v1.2.1) of jsre variable used to have the regexp with url encoded string:
jsre = /=(\?|%3F)/g
so these places should be the placed to be fixed. here's my version of a bug patch code: http://iandeth.dyndns.org/mt/ian/archives/jquery-1.2.3-JSONP-bug/patch.txt
best, toshi

That pattern is no longer supported by jQuery.
Look for John's comments in #2020.
