 * modules & data). Ideal would be to have #process callback
 * work on the form, but FAPI does not call it on forms, despite the
 * documentation stating that it does. In fact, D6 code needs '#input'=TRUE on
 * the element to get into calling #process callbacks. So we set '#input'=>TRUE
 * on the form when inserting our callback into form['#process'], and it forces
 * the FAPI to call that code path and we get our intercept. Works like a charm!
