Attribute Selectors Without Quotes Stopped Working

[stephen@…]

I recently upgraded an app from jQuery 1.4.2 to jQuery 1.5.0. I was using a query like the following:

$('[name=some[field]]')

This stopped working with a syntax error when I used 1.5. I was able to get the query to work with:

$('[name="some[field]"]')

Both queries work in 1.4.2, but the top one fails in 1.4.4 and 1.5.
