/* The accumulated list of undo operations can potentially consume huge
   amounts of memory.  These tuning parameters determine how much undo infor-
   mation is retained.  Normally, the list is kept between UNDO_OP_LIMIT and
   UNDO_OP_TRIMTO in length (when the list reaches UNDO_OP_LIMIT, it is
   trimmed to UNDO_OP_TRIMTO then allowed to grow back to UNDO_OP_LIMIT).

   UNDO_WORRY_LIMIT and UNDO_PURGE_LIMIT take over and cause the list to
   be trimmed back further to keep its size down. */
