- Patch #8632 by Mohse: made the taxonomy select menus more flexible.
  Specifically, it lets you edit more than one node's taxonomy within
  the same form.

  This patch also removes the behavior where taxonomy remembers your
  last choice for a given vocab and automatically selects it for you.
  That is poor behavior.  If someone changes a date or author in a
  node, he is likely to inadvertently add taxo terms using with this
  'feature'.
