function _form_builder_ie_cleanup

6.x form.inc _form_builder_ie_cleanup($form, &$form_state)

In IE, if only one submit button is present, AND the enter key is used to submit the form, no form value is sent for it and our normal button detection code will never detect a match. We call this function after all other button-detection is complete to check for the proper conditions, and treat the single button on the form as 'clicked' if they are met.
