  17  * This file includes code for eating food, drinking potions,
  18  * reading scrolls, aiming wands, using staffs, zapping rods,
  19  * and activating artifacts.
  20  *
  21  * In all cases, if the player becomes "aware" of the item's use
  22  * by testing it, mark it as "aware" and reward some experience
  23  * based on the object's level, always rounding up.  If the player
  24  * remains "unaware", mark that object "kind" as "tried".
  25  *
  26  * This code now correctly handles the unstacking of wands, staffs,
  27  * and rods.  Note the overly paranoid warning about potential pack
  28  * overflow, which allows the player to use and drop a stacked item.
  29  *
  30  * In all "unstacking" scenarios, the "used" object is "carried" as if
  31  * the player had just picked it up.  In particular, this means that if
  32  * the use of an item induces pack overflow, that item will be dropped.
  33  *
  34  * For simplicity, these routines induce a full "pack reorganization"
  35  * which not only combines similar items, but also reorganizes various
  36  * items to obey the current "sorting" method.  This may require about
  37  * 400 item comparisons, but only occasionally.
  38  *
  39  * There may be a BIG problem with any "effect" that can cause "changes"
  40  * to the inventory.  For example, a "scroll of recharging" can cause
  41  * a wand/staff to "disappear", moving the inventory up.  Luckily, the
  42  * scrolls all appear BEFORE the staffs/wands, so this is not a problem.
  43  * But, for example, a "staff of recharging" could cause MAJOR problems.
  44  * In such a case, it will be best to either (1) "postpone" the effect
  45  * until the end of the function, or (2) "change" the effect, say, into
  46  * giving a staff "negative" charges, or "turning a staff into a stick".
  47  * It seems as though a "rod of recharging" might in fact cause problems.
  48  * The basic problem is that the act of recharging (and destroying) an
  49  * item causes the inducer of that action to "move", causing "o_ptr" to
  50  * no longer point at the correct item, with horrifying results.
  51  *
  52  * Note that food/potions/scrolls no longer use bit-flags for effects,
  53  * but instead use the "sval" (which is also used to sort the objects).
