// In most browsers, a <label> tag around a form field, e.g.:
//
//   <label>
//     <input type="checkbox" id="private" name="private">
//     This message is private
//   </label>
//
// works just as if you'd specified a for= attribute on the label
// for the first visible field inside the label.  In Safari 4, this
// seems not to be the case (i.e. the for= attribute is required).
