Selector against name fails if name contains period followed by square brackets

[jonliss]

JQuery 1.3.2 fails if the name used in a selector contains a period followed by square brackets. Either on their own work as expected.

e.g.

$('input[name="foo[0]"]:checked').val() works. $('input[name="fee.foe"]:checked').val() works. $('input[name="bar.baz[0]"]:checked').val() fails.

Attached is a test html file illustrating failure, requires jquery-1.3.2.min.js in same directory.

Tested against Firefox 3.0.15 and IE 6.0.2900 with the same failing results.

For correct cross-browser operation, you must escape any special chars in the name. The W3C says that names can contain only alphanumeric chars, but jQuery allows them in selectors as long as they are escaped with
per the docs.
